The invention provides a packaging film comprising a heat-shrinkable, heat- sealable polyester shrink film. The film comprises a homopolymer or copolymer of polyethylene terephthalate, preferably coated with a solvent-based, heat- seal coating, e.g., an amorphous copolyester. The film may be metallized and/or laminated to other films, e.g., ionomer films. The films and laminated are useful in various packaging applications including cook-in or non-cook bags for packaging meats, as well as lidding applications.
L'invention concerne une feuille d'emballage comprenant une feuille rétractable thermoscellable en polyester. Cette feuille comprend un homopolymère ou un copolymère de polyéthylène téréphtalate recouverte de préférence d'un revêtement de thermoscellage à base de solvant, p. ex. un copolyester amorphe. Cette feuille peut être métallisée et/ou combinée avec d'autres feuilles, p. ex. des feuilles ionomères, pour former un stratifié. Ces feuilles et stratifiés conviennent pour diverses applications d'emballage, notamment pour des sachets se prêtant ou non à la cuisson, destinés à l'emballage de viandes ainsi que pour les applications d'operculage.
