The Torayfan CBS2 comes from Toray. Converter Packaging Products Corp. is the converter who supplies the finished material to Utz. Graphics are reverse-printed on a flexo press.

Hanover, PA-based Utz, which often has to ship products over long distances and has stringent barrier requirements, first used the Torayfan CBS2 BOPP film for its three-ounce party mix, creating a colorful, eye-catching pouch with a clear window that allows customers to see the product. Today Utz uses the material for the packaging of more than two dozen products, including its tortilla chips, party mix, corn chips, Puff N’ Corn, and similar salty snacks in the portfolio that don’t require a metallized lamination.

Will Woodford, Vice President of Sales Administration for PPC, which serves Utz, explains that food manufacturers for years wished for an alternative to transparent barrier film containing PVdC. “Though PVdC-coated OPP film keeps bakery and snack foods fresh and gives consumers a window to the product inside the package, the film has several drawbacks,” Woodford says. “It yellows as it ages, becoming brittle and prone to flex cracking. It has experienced price hikes that have made end-user costs surge, and it has required many flexographic printer/converters to use EMA additives or other supplemental materials to promote bond adhesion for laminating to PVdC-coated OPP. Besides those concerns, reports about PVdC-coated films’ potential negative long-term effect on the environment have made some manufacturers uneasy.”
