PVdC-Free Food Packing Film
Engineering360 News Desk | May 06, 2016A collaboration between Packaging Products Corp. and Toray Plastics has developed a polyvinylidene chloride-free alternative for laminates to pack bakery and snack foods.
A transparent, high-barrier film laminate is the product of a collaboration between Toray Plastics and Packaging Products Corp. Food manufacturers commonly use films containing PVdC to package food products, since the plastic window keeps them fresh and gives consumers a view of the packaged goods. But the resin has several drawbacks, from environmental issues to yellowing and turning brittle with age, as well as some difficulty adhering to other materials.
The new film combines Toray’s CBS2 film and co-extruded BOPP, a laminate that helps to overcome many of the drawbacks of the traditional PVdC-coated BOPP films, according to Toray.
Designed for use as an inside sealant web, the film has been tested for comparison to PVdC-coated BOPP films. In those tests, Toray says the CBS2 BOPP demonstrated favorable moisture and oxygen barrier properties and good lamination bonding qualities. The test results also showed the film to provide good heat-sealing properties, oil resistance, puncture resistance and stiffness, in addition to a longer storage life.
