Flexible Packaging Material Options
Flexible packaging is a solution that businesses turn to for a variety of reasons. For starters, it’s a less-expensive material, but it also offers great durability and product protection. In fact, polyolefin shrink films are a popular high-quality material that is approved by the FDA to increase shelf life.
Flexible films
As you can already tell, there are many different flexible film materials. Here are 14 of the most popular:
(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 be protected from moisture.
(PA) Polyamide – A film that works well as an outer layer, PA provides machinability, a gas/aroma barrier, heat resistance and 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 all of 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 print.
(PVC) Polyvinyl Chloride – A gas/aroma barrier with machinability.
Lamination is the process of bonding a plastic film to a printed sheet by means of heat and pressure for protection of the work or to improve the appearance of the work. The printed cover of books, record cover, jacket etc. laminated with a thin clear transparent acetate film which protect from moisture scratch, wear and tear and also provide a high gloss. Lamination protects paper from tears; spills, wrinkles, and any other substance that could alter the text or graphic were it to make contact with the original paper. It also intensifies colors and improves the overall appearance of printed document and signs. Different projects require a different weight of lamination film, depending on use and location of the item to be laminated, and finishes are available in matte, gloss, or satin.
Ruico have a series of water based film lamination adhesives for wet lamination.
