POLYESTER CONTAINERS AND FILMS WITH REDUCED GAS PERMEABILITY

Three independent approaches to the reduction of gas molecule permeability through a polyethylene terephthalate (PET) polyester film or container wall by increasing the mechanically or thermally induced crystallinity or the overall crystallinity level of a single or multilayer container, where the t...

Beschreibung
Zusammenfassung:	Three independent approaches to the reduction of gas molecule permeability through a polyethylene terephthalate (PET) polyester film or container wall by increasing the mechanically or thermally induced crystallinity or the overall crystallinity level of a single or multilayer container, where the three approaches may be employed independently or in combination with one another. L'invention concerne trois approches indépendantes de la réduction de la perméabilité aux molécules gazeuses à travers un film ou une paroi de récipient de poly(téréphtalate d'éthylène) (PET) polyester par augmentation de la cristallinité induite mécaniquement ou thermiquement ou du niveau de cristallinité global d'un récipient à une ou plusieurs couches, les trois approches pouvant être utilisées indépendamment ou en combinaison les unes avec les autres.
