Toray Plastics (America) Launches Third-Generation Torayfan CB3 Films
Toray Plastics (America) (toraytpa.com) has launched its third generation of Torayfan clear, high-barrier BOPP films.
Consumer demand for fresh, shelf-stable food in transparent packaging and CPG companies’ preference for a PVdC-free, high-barrier film that delivers extended shelf life performance have driven the development of the new high-barrier BOPP films. The Torayfan CB3 portfolio is manufactured with Toray’s proprietary formulation and a patented PVdC-free coating. The films offer oxygen-barrier protection along with excellent moisture barrier and are available in sealable and non-sealable versions. In addition, the 70- and 80-gauge CB3 films are a thinner alternative to thicker OPP films and enable source reduction, yield and economic benefits. The 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 world-class site in North Kingstown, R.I. CB3 films are suited for bags, pouches, stand-up 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,” said Tammy Williamson, associate product manager of the Torayfan Polypropylene Films Division at Toray. “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.
Williamson noted that the CB3 films are also an excellent alternative to acrylic-coated and AlOx-coated films, EVOH sealant web films, and metallized BOPP films. They run on VFFS and HFFS equipment.
