High-strength seals prevent flexible package bursts at high altitudes

Hermetic seals also ensure an excellent seal through any food residue. The proprietary sealant closes channel leaks in challenging seal areas, thus preventing oxygen and moisture from getting into the package and degrading product freshness. The high-performance sealant also prevents any necessary oils in the packaged product from leaking out through the seal areas. Oils that leak can leave a greasy texture on the package surface and stain it and any secondary packaging, compromising the consumer's experience and tarnishing a brand's reputation.

These new films are robust enough to allow a switch from a traditional three-ply lamination to a two-ply structure. Simplifying the converting process promotes production efficiencies, and enables cost savings. It also allows for efficient, multi-channel distribution. Toray's OTM films are designed for use in the manufacture of pillows, pouches, and stand-up pouches (SUP) that are used for salty and savory snacks, cookies, crackers, biscuits, and confectionery items.

"Geographical differences between the four regions of the United States create significant distribution challenges for CPGs," explains Amanda Whaley, Product Manager, Torayfan Division. "With Toray's OTM films the incidence of bags' bursting can be significantly reduced or even eliminated. This innovation gives CPGs the confidence to distribute their products using traditional interstate highways directly over mountain passes. It also opens up new business opportunities for smaller regional manufacturers, who will now be able to distribute products nationwide."

The Over-the-Mountain films are compatible with standard VFFS and HFFS equipment that run heat-sealable BOPP film; no changes in converting set up are necessary. The films are available in transparent, metallized, and white versions in a variety of barrier levels.
