Toray announces new high-altitude packaging film

NORTH KINGSTOWN – Toray Plastics has announced the development of a new biaxially oriented polypropylene film that prevents packaging from bursting while in high altitude or low-atmospheric pressure conditions. Normally, these conditions put extreme stress on the seals of packaging.
The Over-the-Mountain films are made with a modified polypropylene core layer and proprietary sealant that protects the oxygen and moisture barrier. This keeps packaged foods in transit fresher, with the films able to withstand altitudes of about 17,000 feet without a leak, and about 38,000 feet without totally rupturing, said Toray in a press release.
”This innovation gives [consumer packaged goods groups] 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,” without major equipment conversions, said Amanda Whaley, product manager of the Torayfan division.
The sealant also keeps oils in the package from leaking through, protecting the consumer experience and brand image, said the company in a statement.
Toray says the films are strong enough that many companies that use consumer packaging can switch from three-ply to two-ply lamination, and save in production time and costs.
The films are designed for use in manufacturing things like pillows, pouches and stand-up pouches, like the ones used for snacks, crackers and cookies, according to Toray.
