Abstract

A laminated polypropylene-based film suitable for retort packaging having an exterior film, a barrier layer, and a sealing layer. The retort packaging film has a total composition including high levels of polyolefin-based polymers and polypropylene-based polymers such that the material can be processed efficiently in a polypropylene recycling process. Advantageously, the film retains the properties required to suitably withstand the retort process and produce a high-quality shelf-stable packaged product.
