The Torayfan CBS2 film from Toray Plastics is a moisture-barrier BOPP film designed for use as the inside sealant web for the packaging of bakery items, crisp salty snacks, cookies, crackers, granola, fruit and nut mixes, and confections, as well as dry pet food and treats and non-food items.
This transparent PVdC-free laminations reportedly provides an "excellent oxygen and moisture barrier." Versatile, heat-sealable CBS2 BOPP film also offers end users an alternative to coated OPP and PET films and is more economical when compared with aluminum oxide (AlOx)-coated films. In addition, because it's available in 70 and 80 gauge, CBS2 film presents a downgauged alternative to thicker OPP films. CBS2 film can also be used as an unsupported web for flexographic and rotogravure surface printing.
CBS2 film's barrier properties are achieved by means of Toray's resin technology and a proprietary non-PVdC barrier layer. The non-barrier side of CBS2 film is designed for heat sealability. CBS2 film also provides oil and puncture resistance and excellent stiffness, which further improve the consumer's brand experience. The film runs on HFFS and VFFS equipment.
"PVdC is not acceptable to today's end users who want a clear barrier film that is environment-friendly," said Kerri Boyens, product manager of Torayfan division. "PVdC-free CBS2 film is an innovative solution that offers excellent barrier functionality without PVdC's environmental issues."
