Gore Pulp Induction Liner is a unique packaging product that consists of which combines Gore's ePTFE membrane (which is actually polytetrafluoroethylene membrane with microporous structure) with pulp. That blend imparts unique properties to the liner, enabling it to help keep the product fresh as well as preventing the container itself from either mechanically deforming or breaking due to high internal pressures. Pulp form the framework of the liner and holds the ePTFE membrane in position within the container mouth Subsequently, during the pulp induction heating process, the pulp softens and obtains a strong bond with container mouth.
