Toray Plastics (America) has developed the third generation of its Torayfan clear, high-barrier BOPP films.
Driven by consumer demand for fresh, self-stable food in transparent packaging and CPG preferences, the new Torayfan CB3 portfolio is manufactured with Toray’s proprietary formulation and a patented PVdC-free coating. The films offer superior oxygen-barrier protection along with excellent moisture barrier, and are available in sealable and non-sealable versions. In addition, the robust 70- and 80-gauge CB3 films are a thinner alternative to thicker OPP films and enable source reduction, yield and economic benefits. The CB3 films’ strength also enables them to withstand the rigors of the laminating and converting processes without any degradation to barrier performance. All CB3 films are manufactured at Toray’s site in North Kingstown, Rhode Island. CB3 films are suited for bags, pouches, standup pouches and flow wrap. Among their applications are nuts, seeds, salted snacks, cookies, dried fruit and confectionery items.
“The third generation of Torayfan CB films is an exciting advancement,” says Tammy Williamson, associate product manager of the Torayfan Polypropylene Films Division, Toray Plastics (America), Inc. “These are very sophisticated films that combine a modified base film and complex coating to achieve impressive barrier. 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.”
Toray’s new CB3 technology has an oxygen transmission rate (O2TR) of 0.06 cc/100in²/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 the environmental concerns associated with it,” Williamson notes.
