Transparent Standup Pouch

Prepared Foods, March, 2001

Retortable, standup pouches offer weight savings, are easy and safe to open, and their transparency delivers a visual impact on the supermarket shelf.

The transparent film combination for sterilizable applications provides oxygen barrier properties of 1 [cm.sup.3]/[m.sup.2]/d/bar, irrespective of the atmospheric humidity level. It consists of PET as a printing substrate, OPA film with a vacuum-deposited layer of silicon oxide as the barrier layer, and PP as the sealing agent. Since the pouch contains no metallic components, it can be microwaved. The film structure also allows the use of metal detectors on the packaging line.
