Pouches :

Stand-Up Pouches

One of the best alternatives to traditional packaging is stand-up pouches. They function as their name suggests – standing upright on shelves. In addition, this packaging has an airtight closure.

Stand-up pouches (also known as flexible pouches) are extremely easy to pack. They have incredible branding capabilities through digital printing. Stand-up pouches can be custom printed with eye-catching graphics and breathtaking colors.

Stand-up pouches are fully customizable to your needs. And stand-up pouches have multiple barrier layers of protection. As a result, they can suit nearly any product, many of which are listed in the flexible films section below.

Flexible Films

There are many different flexible film materials.

  • (EAA) Ethylene Acrylic Acid – A tie layer between aluminum foil and other polymers.

  • (EVA) Ethylene Vinyl Acetate – An adhesive layer, moisture barrier, and heat-sealable food contact layer.

  • (EVOH) Ethylene Vinyl Alcohol – An oxygen barrier typically placed between PE/PP films, EVOH must be protected from moisture.

  • (PA) Polyamide – A film that works well as an outer layer, PA provides machinability, a gas/aroma barrier, heat resistance. It will not stick to a sealer bar.

  • (PC) Polycarbonate – A moisture and heat-resistant barrier with machinability.

  • (PE) Polyethylene – Another heat-sealable food contact layer, as well as a moisture barrier. It can also be combined with gas/aroma barriers such as (EVOH, PA).

  • (PEN) Polyethylene Naphthalate – A gas/aroma barrier with machinability and heat resistance.

  • (PET) Polyethylene Terephthalate – A film that provides machinability strength, PET is a gas/aroma barrier, moisture barrier, and heat-resistant.

  • (PET-G) Glycol-Modified Polyethylene Terephthalate – A heat-sealable food contact layer.

  • (POF) Cross-Linked Polyolefin – A heat-sealable film best suited for food packaging but also used to laminate print products. Made using a cross-direction technique in which film is stretched both mechanically and manually.
  • (PP) Polypropylene – A moisture barrier that can be combined with other gas/aroma barriers or coated with heat-seal coatings such as acrylate and PVDC.

  • (PS) Polystyrene – A printable and gas-permeable film that can be combined with other gas/aroma barriers.

  • (PVDC) Polyvinylidene Chloride – An O2 barrier and heat-sealable layer that provides gloss and protects the print.

  • (PVC) Polyvinyl Chloride – A gas/aroma barrier with machinability.

Foil Packaging

Foils are used mainly by the food and pharmaceutical industries. Foil packaging keeps food fresh. And, it keeps food safe by blocking contaminants, increasing your products’ shelf life. It is also a recyclable material.

Labels :

Label Materials

Choosing the suitable label material will make all the difference when it comes to printing your labels. There are many different types of paper and film stocks available, and each option is best suited for a specific purpose, print method, and application.

Common paper stocks:

  • Semi-gloss: This material has a sheen to it without looking entirely glossy. Labels are printed directly on semi-gloss paper.

  • High gloss: This paper stock, which labels are directly printed on, has a higher shine than the Semi-gloss.

  • Laser: This paper label is self-explanatory in that it is meant for printers that use lasers rather than ink to create the image.

  • Some standard film face stocks:

  • Polyester: This film is ruggedized for harsh conditions and made to resist tears and scratches.

  • Polyethylene: This material is more malleable and pliant and is often used for labeling curved surfaces like bottles.

  • Polyimide: This heat-resistant film is ideal for electronics and surfaces that may encounter extreme temperatures.

  • Polypropylene: This film is the most common and is relatively inexpensive, used for short-term labeling applications.

  • Vinyl: This stretchy film offers more flexibility while still durable enough to be used in outdoor applications.

Label Adhesives

While label materials are essential in ensuring your labels are printed correctly, a suitable adhesive is just as important. There are several different types of adhesives, and, like the printer material, each is best suited for another purpose.

Common label adhesive types:

  • Permanent: Exactly as it sounds, this adhesive works great for general purposes where a long-term application is needed; however, it may not stick well to certain specialty materials and surfaces.

  • Removable: These labels come in a range of aggressiveness. Some can be removed and replaced repeatedly, and others can only be removed once or twice. Again, it depends on the application and the purpose.

  • All-temp: For environments with extreme temperatures, this adhesive is ideal. Cold-temp and freezer label adhesives fall into this category as well.

  • Aggressive: While “permanent” is well-suited for most applications, sometimes specialty applications call for something more substantial, which is where this type is used.

Shrink Sleeves :

Shrink sleeves provide brand owners with creative product alternatives. However, this also introduces the unique design and operational challenges, like container shape, the equipment in use, the design of the shrink tunnel. Even the product in the container can directly affect the shrink sleeve material.

Polyvinyl chloride (PVC), a material familiar to many, was the primary substrate shrink sleeve label market. It remains in general use today and benefits from a robust and well-developed global supply chain, making it has a lower-cost option. But environmental concerns related to phthalate and chlorine content have been widely communicated. As a result, they have created concerns about using PVC as a shrink sleeve or other packaging material.

The primary material used in shrink sleeve labeling today is Polyethylene Terephthalate Glycol (PETG). The key benefits of PETG use include; its widespread availability, overall film clarity, and shrink capability of up to 80 percent. In combination, these features make PETG generally a good fit for use in most applications. However, PETG shrinks at a much higher rate than other options, which requires proper shrink tunnel conditions to ensure that the shrink sleeve appearance is not compromised.

Paperboard :

Paperboard is a general term used for many different paper substrates used in carded packaging. Card stock is also used similarly, referring to paperboard in general or the backing sheets for stiffening paperboard packaging. Some of the specific types of board include:

  • Cardboard: While some people believe this is another general term, others believe it refers to the materials for corrugated boxes. Cardboard is a heavy-duty paper-based product with greater thickness and superior durability or other specific mechanical attributes to paper, such as foldability, rigidity, and impact resistance.

  • Chipboard: Typically made of recycled paper. Chipboard is a low-grade paperboard option that is best used for padding or dividers but does not offer good printing quality or strength.

  • Clay-Coated Board: This paperboard is coated with fine clay to provide a smooth, bright surface to improve the printing quality. In reality, even though a board may be referred to as “clay-coated,” it may not actually be clay. As well as using other minerals or binding materials may be used.

  • Laminated Board: Two or more layers of paperboard, plastic, or paperboard and another sheeted material may be fused through lamination.

  • Solid Bleached Sulfate (SBS): This high-quality paperboard material is bleached throughout the material, providing a clean white appearance throughout the entire substrate.

    • • C1S or C2S: This stands for clay-coated on one side or two sides. Clay-coated two-sides are used when the package is a two-piece card or a folded card that seals to itself.

    • • SBS-I or SBS-II: These two are solid bleached sulfate materials primarily used for blister cards.

    • • SBS-C: The “C” indicates carton-grade SBS materials. Carton-grade SBS cannot be used for blister card applications. As the surface prevents blister coatings. Conversely, SBS-I or –II can be used for cartons.
