High Pressure Pasteurization Films

High Pressure Processing (HPP) Definition

This is a cold pasteurization technique by which products are already sealed in a final package and are introduced into a vessel and subjected to a high level of isostatic pressure (300- 600 Mpa/ 43,500 to 87,000 psi ) transmitted by water. It is a form of molecular pathology that changes the molecular structure of the product. With this process you can extend the product shelf life without any deterioration in appearance yet offering better shelf life extension of less sophisticated modified atmospheric packaging (MAP).

PPG offers peelable and non peelable lidding films onto containers suitable for the HPP process. Typically trays that can hold up in this process are PET and PP.
