Toray Plastics (America) introduces Barrialox SBR2, a high-barrier, transparent, aluminum oxide-coated polyester film for retort pouch applications.
The film is made in Japan by Toray’s sister company, Toray Advanced Film.
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 consumer goods manufacturers (CPGs) and converters a new generation of ALOX-coated film, which has 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 oxygen- and moisture-barrier durability. Typical value, flat sheet oxygen- and moisture-barrier transmission rates for Barrialox SBR2 are 0.01cc/100 inches and 0.02 g/100 inches, respectively.
Chris Voght, senior director of sales and marketing, Torayfan Division notes that brand owners continue to choose the retort pouch for traditional applications, such as seafood, chicken, prepared meals, rice, and even pet food.
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 more than aluminum oxide-coated films.
In standard laminations, SBR2 is reverse-printed to create a colorful, attractive package that can be microwaved.
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.
