Abstract: front page image
(EN)Coextruded, biaxially oriented, heat-shrinkable films having a base layer comprising a polyester having an intrinsic viscosity greater than 0.75 and at least one outer heat-sealable layer directly adhered to the base layer are disclosed. The outer layer is heat-sealable and optionally peelable in particular to polyester containers. The invention further relates to a process for producing the film and to packages comprising a container, a product and the coextruded, biaxially-oriented heat-shrinkable film sealed onto the container. The packages are suitable for use with ready-prepared foods, so-called 'ready-meals', which are intended to be warmed in a microwave or in a conventional oven.
(FR)L'invention concerne des films coextrudés, orientés biaxialement et thermorétractables comportant une couche de base comprenant un polyester ayant une viscosité intrinsèque supérieure à 0,75 et au moins une couche externe thermo-scellable adhérant directement à la couche de base. La couche externe est thermo-scellable et éventuellement détachable, notamment sur des contenants en polyester. L'invention concerne également un procédé de fabrication du film et des emballages comprenant un contenant, un produit et le film coextrudé, orienté biaxialement et thermorétractable scellé sur le contenant. Les emballages conviennent à une utilisation avec des aliments préparés prêts à consommer, dits « plats cuisinés », destinés à être réchauffés dans un micro-ondes ou dans un four traditionnel.
