High-Barrier Transparent PET Film suits retort pouch applications.

Press Release Summary:

Used to produce transparent, printable, and microwaveable packaging, Barrialox® SBR2 aluminum oxide-coated polyester film resists pinholing, flex-cracking, and scuffing/abrasion. Thermal stability and such mechanical properties as strength and dimensional stability enable product to withstand converting process conditions and retort sterilization heat/pressure. Typical value, flat sheet oxygen- and moisture-barrier transmission rates are, respectively, 0.01 cc/100 in. and 0.02 g/100 in.

Toray Plastics (America) Presents New Barrialox® SBR2 High-Barrier, Transparent Aluminum Oxide-Coated PET Film for Retort Applications

Robust, transparent, printable, and microwaveable packaging allows consumers to see the food.

North Kingstown, Rhode Island -- Toray Plastics (America), Inc., (www.toraytpa.com), the only United States manufacturer of polypropylene, polyester, metallized, and bio-based films, announces the introduction of Barrialox® SBR2, a new high-barrier, transparent, aluminum oxide-coated polyester film for retort pouch applications, which is made in Japan by Toray's sister company, Toray Advanced Film Co., Ltd http://www.toray-taf.co.jp/en/index.html. The retort pouch, which is used to package cooked, sterilized food, has gained wide acceptance among consumers who value the convenience of microwaveable meals and "on-the-go" foods. Barrialox SBR2 film offers CPGs and converters a new generation of ALOX-coated film, which has excellent thermal stability and superior mechanical properties, including high-strength and dimensional stability, enabling it to withstand the rigors of the converting process and the intense high heat and pressure of retort sterilization. The film's strength and resilience contributes to the production of a finished, post-retort pouch that has excellent oxygen- and moisture-barrier durability. Typical value, flat sheet oxygen- and moisture-barrier transmission rates for Barrialox SBR2 are 0.01cc/100 in. and 0.02grams/100 in, respectively.

"A film that maintains its inherent barrier-durability during and after converting and retorting processes is essential for a successful retort application," says Chris Voght, Senior Director of Sales and Marketing, Torayfan Division.

Voght notes that brand owners continue to choose the retort pouch for traditional applications, such as seafood, chicken, prepared meals, rice, and even pet food, but they also want it for new product introductions and brand extensions, especially microwaveable applications and when the CPG wants customers to see the food. "Microwaveable vegetables and sauces, in particular, are trending now," he says.

Barrialox SBR2 resists pinholing, flex-cracking, and scuffing and abrasion, making it a preferred choice over more delicate aluminum oxide-coated films. In standard laminations, SBR2 is reverse-printed to create a colorful, attractive package that can be microwaved. "Overall, Barrialox SBR2 is an excellent option for gusseted and non-gussetted retort pouch laminations," he says.

To manufacture a pouch with added convenience and exceptionally high heat-seal strengths, Barrialox SBR2 can be laminated with Toray's TreaTear® DR72 film. TreaTear DR72 is a directional-tear CPP sealant film that provides an easy, straight tear for opening the package. Barrialox SBR2 can also be used in the manufacture of non-retort clear packaging and in lidding lamination applications.
