Consumer demand for fresh, shelf-stable food in transparent packaging and consumer packaged goods (CPG) companies’ preference for a PVDC-free, high-barrier film have driven the development of a third generation of Torayfan film by Toray Plastics (America). A subsidiary of Tokyo-based Toray Industries, the company is headquartered in North Kingstown, RI.
The new Torayfan CB3 portfolio is manufactured with Toray’s proprietary formulation and a patented PVDC-free coating. The films feature oxygen- and moisture-barrier protection and are available in sealable and non-sealable versions. The robust 70- and 80-gauge CB3 films are an alternative to thicker OPP films and enable source reduction, yield and economic benefits.
The films are sufficiently strong to withstand the rigors of laminating and converting processes without any degradation to barrier performance. All CB3 films are manufactured at Toray’s world-class site in North Kingstown, RI. Applications include bags, pouches and stand-up pouches containing nuts, seeds, salted snacks, cookies, dried fruit and confectionery items.
“These are very sophisticated films that combine a modified base film and complex coating to achieve impressive barrier properties,” said Tammy Williamson, Associate Product Manager of the Torayfan Polypropylene Films Division. “In addition, consumers today want to see the item they are purchasing; it helps them feel confident that the food and ingredients are fresh. CB3 films offer the transparency and freshness protection they expect.”
Williamson added that Toray’s new CB3 technology has an oxygen transmission rate of 0.06 cc/100 in²/day at 73°F, 0% RH, without any compromise to moisture-barrier properties. The previous generation of CB films has an O2TR value of 0.25. In cases where end users are using a lamination made with PVDC-coated PET and a sealant web, the CB3 OPP films offer a significant improvement in both moisture and oxygen barrier.
“Also important is CPG companies’ preference that PVDC be eliminated from packaging because of environmental concerns. They appreciate Toray’s commitment to sustainability,” Williamson said. “Now manufacturers are able to specify a transparent package with even greater shelf stability, without PVDC issues.”
Williamson noted that the CB3 films are also an alternative to acrylic-coated and AlOx-coated films, EVOH sealant web films and metalized BOPP films. They run on vertical and horizontal form, fill and seal equipment.
