A new mid-level oxygen-barrier film released on the market adds to
the choices processors have for packaging foods and liquids.

Preventing oxygen permeation through plastic packaging is a major issue in the food industry. The oxidation of foods or liquids reduces shelf life, and affects the sensory properties. Honeywell Specialty Films introduced the new film as part of its current OxyShield range of nylon barrier packaging for food manufacturers. The new mid-level oxygen-barrier film, OxyShield Plus, is composed of biaxially oriented layers of ethylene-vinyl alcohol copolymer (EVOH) sandwiched by nylon. "It has outstanding resistance to solvents, oils and greases that is common to both materials,"​ Honeywell claimed. "The product also offers superior mechanical properties, good transparency and gloss, easy printing and lamination, and resistance to flex cracking."​ In addition to releasing the new film Honeywell said it has also fully commercialised its OxyShield inline polyvinylidenechloride (PVdC) coated biaxially oriented nylon film (BOPA). The film has an improved oxygen and moisture barrier through the coatings, the company claimed. Both developments are part of the company's strategy to offer a complete line of nylon 6-based films for all oxygen barrier needs, said Jeff Czarnecki, business director for Honeywell's specialty films business. "Our customers increasingly have varied barrier needs for film packaging and can expect an even higher barrier OxyShield film as we complete our full product portfolio in the near future,"​ he said. Honeywell's OxyShield's films are designed to provide clarity and are microwavable. They also are metal detection friendly, Honeywell stated. OxyShield is currently used for packaging oxygen-sensitive, shelf-stable foods for human consumption or for pet foods that need packaging resistant to odors, aromas, oils and greases. Honeywell produces films and resins in Pennsylvania, Louisiana, and Dangjin, South Korea.
