It's in the Bag

Most of the materials used with pouches are of the main-stream variety, said Zehr, such as PET, OPP, nylon, PE, and COEX sealants, and extruded foil-based structures. Stern said his company prints pouches on PET, BOPP, or BONYL, but believes PET is the best choice since "it allows us to deliver very sharp outlines, details, small lettering and provides great gloss."
