The front and the back of the carton are marked in the keyline. The ultimate definition of which side of the carton should be the front can only be made by the customer. Among other factors, the planned positioning of the carton on the shelves must be considered.

Print inspections and approvals are carried out at our cylinder suppliers. The point of the press proof produced in this case is to create a color-accurate rendering of the approved color proof. However, minor color corrections are possible. The press proof approved in the print inspection and approval, and not the color proof, is then the binding color-accurate proof for the production of the packaging material.

At the present time, there are no options for refinements.

Recently, there has been an incredible amount of verbal and written media coverage on BPA, which has caused many to wonder if they are being exposed to it, and what the resulting health affects are. Today, within its product portfolio, SIG has zero bags and pouches that contain–or are made with–BPA. An official letter on this topic has been issued by SIG. So, regardless if BPA does or does not have negative health affects, it is not found in SIG's bags and pouches; therefore, not a risk to its customers.

What is BPA?

Bisphenol A (BPA) is a molecule most commonly used in the production of polycarbonate (PC) and epoxy resins. Common applications where PC resins are used are automotive light covers, compact disks, and water bottles; overall, it has an excellent combination of clarity, heat resistance, and stiffness. With its outstanding adhesion to a variety of substrates, epoxy resins are commonly used as adhesives and protective coatings.

Within the above mentioned media coverage, some uninformed journalists have made a direct link between BPA and the recycling symbol number 7, which is formally designated as all “Other” materials not included in recycling symbol numbers 1 to 6. While small portions of recycling symbol number 7 packages do contain BPA, the way it has been presented has been misleading.

Often multiple non-BPA materials are combined to satisfy barrier and performance requirements that result in them being classified as recycling symbol number 7. One example of this is SIG's HyBar product line, which combines polyethylene terephthalate (PET: recycling symbol number 1) with low density polyethylene (LDPE: recycling symbol number 4) to form a laminated film that has outstanding oxygen protection and physical strength. Simply put, there are many recycling symbol number 7 packages that do not contain BPA.

In all cartons with lateral longitudinal seam, the back is 3mm narrower. The missing area is made up from the left lateral surface. To avoid elements being truncated, the type area limits must be observed.

Color approvals cannot be given using PDF files. Depending on the viewer's monitor/printer, the reproduction of the colors is very variable and is not color-accurate. PDF files are used for the approval of text, layout, EAN code and opening aids.

Some of SIG’s bag-in-box bags and taps are recyclable where Resin Identification Code (RIC) 7 is accepted. RIC 7, or “Other,” refers to products containing mixed plastics or those which might have additional components including non-petroleum-based plastics. If a SIG product is marked as RIC 7, it is likely because the tap or spout has a different type of plastic than the bag itself.

Some of SIG’s bag-in-box bags and taps are marked as RIC 4, or “LDPE.” Low-density polyethylene is a common plastic used in flexible packaging and is easily recyclable by most municipalities.

As always, recyclability of bag-in-box bags is contingent upon the disposal requirements of the product contained and the capabilities of the local municipality.

Yes, because of the different cut-outs for the opening aids and the different technical points per opening aid, the design must be adjusted. Depending on decor and/or the configuration of the carton top, one or even several new printing plates must be produced.

The size of the EAN code must conform at least to SC01 (91%). The positioning of the code should be vertical (orientation of the bars in print direction).

Metallic colors cannot be colour-accurately represented on the proofs. If metallic colors are used, we will provide you with real color cards with the required metallic shade. For the colors in question, the color card selected, and not the proof, would therefore be binding and color-accurate.

For the first reprographic composition and for substantial corrections, 5 working days are required. Simple or minor corrections (such as changes to text, for instance) can be done within 2 to 3 working days. For further details, please refer to the infographic on our processing times.

Flexible packaging, unlike rigid packaging, has the ability to increase the product-to-package ratio, reducing overall waste from excess packaging and product that would have otherwise been left in the package.

With less material required in production and a resulting lower material weight in flexible packaging systems, this method of packaging results in less post-consumer solid waste. This means that after a consumer is done using the product and its packaging, there will be less of the package content to dispose of than, for example, glass or aluminum. In addition, a large portion of flexible packaging volume comes from corrugate, which is highly recyclable and is able to be reused, therefore reducing the amount of waste that ends up in landfills after use.*

Outside of this, flexible packaging helps to prolong the open shelf life of products. Since the package collapses on itself as the product is evacuated, air cannot enter the package and degrade the product quality.

Different packaging filling conditions affect storage requirements, shelf life, and ultimately the quality of the product. The below chart looks at ambient, extended shelf life, hot-fill, aseptic high-acid, aseptic low-acid and retort filling conditions.

Also learn why aseptic processing and packaging can produce a more high-quality product than Hot-fill or Retort processing. 

The cartonboard has a layer of high-quality polyethylene (PE) inside and outside. There is also a razor-thin aluminum layer and a further PE layer on the inside. The printing is done on the outermost PE layer. This means the printed color will not be further laminated over.

Generally, up to six colors can be used. However, the use of five colors increases flexibility within the production process and thus gives shorter processing times.

Carrying over data is generally possible. But the data must be adjusted to the keyline of the SIG packaging system. The greater the variation between the dimensions of the individual side parts, the more complex the conversion, and it may not be possible to avoid altering the design.

In principle yes, but the following points must be borne in mind.

- Only one multiple-blank is considered to be binding for colour accuracy; the others result accordingly.

- The maximum number of multiple-blanks possible is based on the overall multiple-blanks of the printing form, which is format-dependent.

- No sorting of the multiple-blanks is possible after production.

In parallel with the decor approval, the packaging material order must be received. Without a packaging material order, the engraving of the cylinder, and therefore the production of the packaging material, will not be set in motion.

The proof is accurate and binding for all colors represented. This does not apply for metallic colors and a few colors which cannot be represented within the proofer color space. In these cases, the colors concerned will be rendered using real (press-proofed) color cards. On the proof, these colors will be marked as 'not binding and color-accurate'.

The printing of white is not possible. Generally, the use of white is not necessary, as the print substrate is sufficiently white.

There is no dot gain in the gravure printing process.

To ensure a logical connection, in the design phase a connection which is as simple as possible should be incorporated. Small elements or text should be avoided in this area. Otherwise there is a danger of elements being partially truncated, or appearing twice. Due to possible production tolerances, this cannot be avoided.

SIG has its own color system. Depending on the colors used in the decor, a color profile will be individually devised. This profile simulates, on the one hand, the color rendering, but also typographical characteristics and the print substrate.

For the approval of the decor, the customer/agency generally receives an Epson proof. This proof is binding for texts, colors and for the layout. If color corrections are required, these must be re-represented using a new Epson proof. Smaller amendments such as text changes, movement of elements etc. can be represented using a PDF file, provided that a color approval has been given via an Epson proof.

A typical retail bag-in-box package can look similar to any of the below images. It typically consists of a bag and a box. The bag is made from a variety of plastic films, with a spout and cap or tap sealed onto it for dispensing the liquid inside. The box is typically corrugate, sized and fluted to the specifications of the product it contains. Retail bag-in-box packages can be found in the food, beverage, and non-food sectors, in sizes from 1L to 10L.

Trends of note in this space include:

• Storytelling Packaging: Brands can take their packaging to the next level, making the package a tool to communicate their brand story. Online brands  don’t have the luxury of getting their products into the hands of consumers before purchase, so designs must work harder than those in brick and mortar stores.*
• Ecologically-Aware Packaging: Brands are looking to minimize the amount of materials needed to package their products** – flexible packaging provides excellent source reduction.
• New Packaging Formats: More and more brands are looking to branch out from traditional package formats – like bottles and cans – and into new packaging concepts. Each year we can see a lot of concepts that play with different forms of packages, so expect to see new forms for traditional products.**

Shelf stable means that the filled package can be stored for long periods of time in ambient conditions without refrigeration or freezing. Some liquids are naturally shelf stable, and do not spoil, while others have to be processed and filled via hot-fill or aseptic to achieve the required sterility so that they can be treated as such.

Non-perishable products such as these include canned and bottled foods, rice, pasta, and foods processed in aseptic packages. In order to be treated as shelf stable, “perishable food must be treated by heat and/or dried to destroy foodborne microorganisms that could cause illness or spoil foods.”* Our aseptic bag-in-box packaging provides the treatment necessary to maintain its sterility for products to be able to sit on shelves for an extended period of time, and thus be considered shelf stable.

Closed-loop dispensing systems are systems where both the product and dispenser interface are completely closed, before, during, and after the dispensing process. This eliminates contact exposure. “These systems offer safety and convenience by minimizing opportunities for contamination while in-use and extending freshness upon opening.” Closed-loop dispensing can be used in both bath-in-box and pouch packaging.

According to the Sustainable Packaging Coalition, a sustainable package is:

• Is beneficial, safe and healthy for individuals and communities throughout its life cycle.
• Meets market criteria for performance and cost.
• Is sourced, manufactured, transported, and recycled using renewable energy.
• Maximizes the use of renewable or recycled source materials.
• Is manufactured using clean production technologies and best practices.
• Is made from materials healthy in all probable end-of-life scenarios.
• Is physically designed to optimize materials and energy.
• Is effectively recovered and utilized in biological and/or industrial cradle-to-cradle cycles.

UN packaging requirements involve a series of protocols to guarantee safety during the transportation and storage of goods. UN packaging testing is a series of tests and requirements to determine the integrity and safety of the package when facing various situations. Once a package has undergone a series of safety tests, the package is considered safe for transportation and is UN-Certifiable.*

Tests conducted in this process include testing for leakage, reactions to pressure, ability to undergo stacking, and resistance to piercing. After all testing is completed, and a report has been drawn up to show that they were successful, a package is considered UN-Certified.*

Foods and beverages that are retailed and stored in normal room temperature are called ambient food.* Also known as fresh, this packaging occurs when a product is filled into a package with no additional sterilization treatment. Ambient packaging treatment fights off harmful microorganisms with heat to avoid contamination to food products.* With ambient-filled food or beverage packaging, the products must either be refrigerated or frozen in order to maintain their shelf life.

Aseptic filling is a processing technique that makes it possible to package items that are shelf stable without preservatives. Items that are packaged aseptically do not need to be refrigerated and can be safely consumed for up to twelve months.

The FDA has developed a set of standards for aseptic filling because it is used for so many products, particularly food and pharmaceuticals.

How does aseptic filling work?

Aseptic filling works by introducing a pre-sterilized product into a pre-sterilized container. Items are sterilized using ultra-high temperatures for a few seconds at a time.

By keeping all parts of the filling process sterile, harmful microorganisms are kept out of the final package and there’s no need for refrigeration. This is done in four steps:

• One: The product to be packaged is sterilized, cooled, and put into a filling machine
• Two: We send pre-sterilized packaging that is safe and ready for you to use
• Three: External package surfaces are re-sterilized using our Vapor Sterilant Technology™
• Four: The package enters a pre-sterilized environment and is filled and hermetically sealed

Some examples of items that are commonly packaged using aseptic technology are milk, coffee, and fruits and vegetables. Items retain their original flavor, color, and nutritional value while retaining their freshness.

Bag-in-box packaging utilizes a box, bag, and fitment to transport and dispense liquid products both efficiently and without contamination.

• Bag: The bag is constructed from layers of film that are sealed together and designed to protect the product quality and keep it safe inside from filling through end use.
• Spout: The foundation of our all bag-in-box fitments, this plastic-framed opening is sealed into the bag when it’s made and is the entry point for filling the product into the bag. After filling, bag spouts are covered by either a simple cap, dispensing tap, or connector and fitment depending on their intended end-use.
• Fitment: This is a broader category of items including spouts, caps, valves, and more. It encompasses anything that attaches to the bag spout. Bag-in-box fitments can be anything from simple caps that cover a spout, to sophisticated dispensing valves or connecters and hoses that bridge between the spout/valve and outside dispensing equipment.
• Box: the outer package that holds the capped and filled bag. This can be anything from a simple cardboard box to an industrial-sized steel drum.

The bag is first filled with liquid product, and then a fitment is placed to secure the packaging. The bag is then placed in a box to ensure safety in transportation and dispensing.

Bag-in-box history

Bag-in-box was pioneered and patented by William R. Scholle in 1955, and it was initially used to safely transport battery acid to automotive filling stations and repair shops. While only starting off in the automotive industry, this packaging system quickly spread to other industries. After the aseptic filling process was perfected in 1956, bag-in-box was able to expand into working with food and beverage products. Learn about the roll Scholle IPN played in developing aseptic packaging.

*Co-extruded film is a multilayer film produced by a compound molding technique that extrudes thermoplastic resin with multiple extruders and passes that through a single die to build up layers of melted resin both on the inside and outside of a film. A film can be produced on a blown film or cast film extrusion line. It can be made with one layer or multiple layers of material. When a film is made with one layer of material, it is called a mono-layer film. When it is made with multiple layers of material, it is called co-extruded film. Scholle IPN uses blown film extrusion and has lines with up to 9 layers of film. Some examples of our co-extruded films include the 7-layer EnduraShield Advance and the 5-layer FlexiShield Advance.

Laminates are created when a piece of equipment takes two (a structure called duplex) or three (a structure called triplex) films and adheres (or bonds) them together. SIG uses solvent-free technologies for this process for both adhesive and thermal lamination. Laminates are used for a variety of flowable products, and SIG’s unique structures are designed to keep products safe while extending their shelf life. Laminates can be used in combination with fitments and filling equipment to create a complete solution to meet all needs.

When it comes to printed film, we offer printed roll stock using flexo or roto technology. This print can be on the surface of a film, or reverse printed on a substrate and then laminate to protect it inside the structure. Learn more about one of our film manufacturing locations here!

In a “gravity-dispense” package,  the cap is removed from the package and a valve is attached to the spout. The package is then hung in a rack that points the valve downward. Gravity then forces the product to flow when the valve is opened.

Horizontal Form-Fill-Seal is a piece of equipment that both produces a pouch from roll stock film and spout and cap assemblies, and fills it in the same operation. The film or laminate travels through the machine in a horizontal direction, which gives the machine the “horizontal” description. This process accounts for all parts of manufacturing a complete pouch product, from film unwinding, pouch forming, filling and sealing, as seen below. A benefit of HFFS is that it optimizes the total cost of ownership and allows for more flexibility in sizes and shapes in production. It also provides the manufacturer with total control of their packaging process.

Hot-fill packaging is a way of sterilizing the package prior to the filling process to ensure the protection and longevity of shelf life for a wide range of products. This process works by first filling heated, commercially-sterile products in non-sterile packaging. This means that the liquid is heated to near boiling (~ 92 Celsius) before it is filled into the package. Once filled, the package is inverted so that the hot liquid comes in contact with all of the package’s internal surfaces. It is then held at a high temperature for a set period of time, before it is cooled to room temperature. Only high-acid products can be hot-filled and held at ambient temperatures without refrigeration.

Pouch packaging is a flexible packaging product made from barrier film, foil, and spout and cap fitments that supports flowable liquid products. Pouches are designed with the flexible needs of the consumer in mind, as there are flexible sizing options to fit any product.

With CleanPouch Aseptic, pouches are able to be stored in ambient temperatures and products maintain their freshness for long periods of time. Pouches are lightweight, compact, and have minimal product waste because of its flexible material that breaks down as it is used. Recycle-ready pouch options are also available using RecShield barrier film.

Pour-out packaging is where the user pours the product from the bag-in-box package (either from the box or bag). The fitments for pour-out packaging are typically simple spouts with an over-cap.

Pump-out packaging is where the bag has some sort of adaptor type cap that attaches to a hose and pump by a connector. The pump then pulls the product from the bag and delivered to a remote location. Operation of the pump is either automatically controlled by a CO2 pump or by the user operating a manual pump lever.

Slash-and-serve packaging is where the bag is cut and the product dumped out of the bag and into another vessel.

Source reduction means minimizing waste before it’s created. It means using less to make packaging and products. Right now, over 60% of all materials are landfilled or incinerated. Approaching this problem from a source reduction standpoint would ask companies to eliminate wasteful practices and invest in technologies that improve efficiency in packaging. This can take on a few forms:

• Using fewer materials to create a product
• Cutting the weight or volume of an item
• Simplifying the supply stream or an item’s transportation needs
• Bringing production in-house to avoid shipping overhead

Eliminating waste is fundamental to building a circular economy. Committing to source reduction isn’t a fixed set of principles, but rather an overall approach to how we pick, design, and transport materials. Some choices are more obvious than others: developing recycle-ready films is a tangible step towards source reduction, while designing fitments that require no threading and use less plastic is an important, but perhaps less obvious step towards source reduction.

At Scholle IPN, source reduction is a key tenet to how we approach sustainability. Our flexible packaging has a higher product-to-package ratio, which means more of an item can be packaged with fewer materials. Our aseptic technology means we can eliminate refrigeration and cold storage throughout the supply stream. Source reduction happens at every step of the supply chain and is one of the most impactful ways companies can build a more sustainable future.

The FDA CFR113 defines low-acid foods (other than alcoholic beverages) as having a finished equilibrium pH greater than 4.6 and a water activity (aw) greater than .85. For example, tomato products having a finished equilibrium pH less than 4.7 are not classified as low-acid foods. The division between low-acid and high-acid foods is based on the limited pH growth of clostridium botulinim.

• High-acid products have a pH lower than 4.6
• Low-acid products have a pH level higher than 4.6

Trapping means: overfilling. Because the printing process involves printing a number of colors on top of each other and side by side, trapping is applied due to unavoidable register variations in the printing process. Otherwise, white edges, known as streaks, can develop at the points where two print colors meet.

Aseptic processing and packaging is the filling of commercially-sterilized products into pre-sterilized containers.

1. After you process, commercially sterilize, and cool your product, it’s ready to deliver to the filler.
2. We pre-sterilize incoming flexible packaging, so when it arrives at your location, it’s safe and ready for aseptic filling.
3. The external surfaces of the cap and spout are then re-sterilized with our patented Vapor Sterilant Technology™ (VST).
4. Your flexible package then enters a pre-sterilized, enclosed atmosphere that is free of microorganisms, where the cap is removed to begin the filling process. Filling takes place through the spout. The cap is then hermetically sealed onto the spout, creating a contained sterile package for your aseptic product.

Hot Fill Processing

Hot-fill takes place when you fill heated, commercially-sterile product in non-sterile packaging. The product is held for a predetermined time and temperature in order to sterilize the packaging prior to the filling process. The longer hold time at high temperatures reduces quality of the product. Only high-acid products can be hot-filled and held at ambient temperatures without refrigeration.

Retort Processing

Retort takes place when you fill non-sterile product in hermetically-sealed, non-sterile packaging. The packaging is loaded into a retort pressure vessel and subjected to pressurized steam.  The product is also exposed to high temperatures for a much longer period than in hot-filling. The additional time can significantly deteriorate the overall quality and nutritional content of the product.

Aseptic Processing

Aseptic is a desirable alternative to hot-fill or retort processing because it doesn’t expose products to extended periods of high thermal temperatures, which can lead to vitamin, color, taste, and texture degradation. The aseptic process ultimately ensures a better quality product that can still maintain shelf-stable distribution.

The printing is done using the rotogravure printing method. The exception to this is the SIG SafeBloc product, which is made using the flexographic printing process.

In the 1970’s, SIG developed the aseptic filling machine which enabled the bag-in-box packaging process. Prior to SIF, the aseptic process had been limited to cans and was most commonly used for dairy products. Aseptic packaging for bulk bag-in-box allowed processors to provide out-of-season products throughout the year, revolutionizing the storage and transportation of processed fruit and vegetable products.

In recent years, we have seen a shift in consumer demands towards healthy beverage options, resulting in the growth of the aseptic drink category. SIG's advancements in filling equipment and bag-in-box technology provide solutions for retail and institutional establishments who wish to offer coffee, dairy, juice, smoothies, and other functional beverages, while retaining nutritional value.

The Materials Science Lab has equipment to support analytical testing, application testing, and mechanical testing for film, bags, fitments, and pouches.

Testing is all about determining fitness for use. The lab team develops tests by looking at what products go through in every part of the process from production through end use. The lab team then distills that whole process into a few reliable tests that can be done in the lab to determine fitness for use in a timely fashion. Our tests and testing equipment includes:

• Vibration Table
• Material Durability Analysis
•  Gelbo Flex Resistance
•  Drop Testing
• Evacuation Tests
• OTR (oxygen transmission rate)
•  Fitment Testing
•  Tensile, elongation, tear, and puncture tests for barrier films
•  Pilot Line for New Film Trials
• ... and More!

FSC labelling must be applied in accordance with the specifications of the FSC Labelling Guideline.

This is called trapping, a feature that is applied to the gravure-printable data in the reprographic composition. This helps minimise possible register variation within the production. Trapping ensures that white streaks and fuzzy edges are avoided.

Special colors are used in order to make the design printing as stable as possible. In the color simulation, production tolerances such as register variations and color drift are possible - there can be minimised by the use of special colors.

Colours from color systems such as Pantone are not used in the SIG print process. Food regulations and the carton material limit the choice of colors. In the reprographic composition, the Pantone color specs are adjusted to match SIG's C colors as closely as possible (see SIG Color Guide), and reproduced on the color-accurate proof. 

Using the SIG Color Guide to define the required colors right from the design planning stage can avoid subsequent colour adjustments with unnecessary rounds of corrections. This would therefore reduce the processing time for the decor.

The proof created by SIG is based on profiles which simulate the printing process at SIG. In the creation of these profiles, the substrate to be printed, the colors used and the actual printing process are taken into consideration. Because of this complex preparatory work, we're able to ensure that the proofs issued are virtually 100% color-accurate. In addition, the proof is generated from the data which ultimately will also be used for the engraving process. With the re-approval, we also want to ensure that the most recent status of the data corresponds to the customer's requirements.

All colors represented are based on color profiles created specially for SIG. For technical reasons, however, in one color profile a maximum of 4 colors can be rendered in the overprint. If more than four colors are to be printed on top of each other in the decor, a second profile must be used. The first proof would therefore, for instance, present the image in binding color-accurate form, while the second proof would reproduce the background correctly.

The dots displayed simulate what are known as 'missing dots', which can appear during the production process. Missing dots are depressions in the print substrate into which no ink is transferred. The number of white dots varies depending on tonal value, and diminishes with increasing tonal value. The simulation cannot reflect the reality 100%. During production, the actual number of missing dots can turn out to be a lot more, or a lot less.

Refrigeration serves to slow or prevent the growth of microorganisms in the product.

Products that are aseptically processed are commercially sterilized to kill harmful microorganisms. These products are filled into a sterilized package using a sterile filler.

Since both the product and package have been sterilized, the sealed package is shelf-stable and refrigeration is not required.

The majority of consumers shop online—and that’s no surprise to anybody. In the United States alone, ecommerce sales reached an estimated $591 billion dollars⁽¹⁾, and globally ecommerce sales are expected to reach $4.9 trillion in 2021⁽²⁾. Over half of all millennials prefer shopping online versus in-person⁽³⁾, and the COVID-19 pandemic has made online sales a necessity for people looking to get their products safely. And as the above numbers suggest, online sales are only going to continue to grow and reshape the way consumers buy products.

Mintel research indicates that only 11% of ecommerce customers are completely satisfied with the way their packages are received. How common is it to order something small and receive a package that feels redundant? Perhaps a box within a box? Or maybe dozens of torn up pieces of paper and tissue, meant to pad your purchase, only to be broken in transit?

As easy as it is to order online, it’s also easy to review products and purchases, so the final moment when a consumer opens a package is critical. 77% of millennials trust written reviews on websites like Amazon and Yelp just as much as they do a verbal recommendation⁽⁴⁾. A few complaints about wasteful packaging or damaged products can be enough to tank a product’s online reliability.

Improving your customer’s ecommerce experience is crucial to the viability of your business, and flexible packaging gives your customers a satisfying ecommerce experience. Not only does our flexible packaging reduce touch points along the supply chain, it reduces the risk of damage in transit with both Compact by Design and SIOC-approved solutions.

Earning trust from your customers isn’t just about providing an excellent product, but about aligning all parts of the ecommerce experience with your company values. A sustainably-packaged item wrapped with care speaks volumes. To learn more about packaging for ecommerce, check out this webinar.

In principle, implementation in CMYK is possible. But this is dependent on the design and the colors used. We do not print - as is frequent practice in offset printing - with the standard process colors; instead, to ensure maximum production stability we define the color composition using special colors, depending on the design. Normally, CMY are used for photo-realistic images, and a brand color and a text color are defined. On this, see also the next question 'Why are special colors used?'.

Due to register variations, negative white texts can be illegible in multi-colored surrounding. We therefore recommend printing the texts concerned positively on a brightened surface. If negative white texts are unavoidable, an outline must be created around the text. Alternatively, the outline could be replaced by trapping of a high-contrast color.

SIG offers four different metallic colors (one silver and three gold variants). We'll be happy to provide you with samples. Please request these from us.
