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 Toray Plastics (America)’s third generation of Torayfan clear,
high-barrier BOPP films. 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 world-class site in North Kingstown, Rhode Island. 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,” 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.”
Williamson notes that 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,” she says, “is CPG companies’
preference that PVdC be eliminated from packaging because of the environmental
concerns associated with it. They also appreciate Toray’s commitment to
sustainability. Now manufacturers are able to specify a transparent package
with even greater shelf stability, without PVdC issues.”
Williamson notes 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.
