A new mid-level oxygen-barrier film for packaging foods and liquids

26-Oct-07
Preventing oxygen permeation through plastic packaging reduces food oxidation. The oxidation of foods or liquids reduces shelf life, and affects the sensory properties, and is a major issue in the food industry. Honeywell Specialty Films has 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 and also offers superior mechanical properties, good transparency and gloss, easy printing and lamination, and resistance to flex cracking. Honeywell 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. Both developments are part of the company's strategy to offer a complete line of nylon 6-based films for all oxygen barrier needs 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.
