Toray Plastics has introduced Barrialox SBR2, a new high-barrier, transparent, aluminum oxide-coated polyester film for retort pouch applications. The product is made in Japan by Toray’s sister company, Toray Advanced Film Co., Ltd. The retort pouch, which is used to package cooked, sterilized food, has gained 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, featuring thermal stability and enhanced mechanical properties. The high-strength and dimensional stability enables 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.

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. To manufacture a pouch with added convenience and 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 asy, 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.
