Patent

CA 2659764

The present invention relates to a sealable, thermoformable, heat-shrinkable multi-layer film having a symmetrical construction around a two-ply inner layer, and having a heat-shrinkability in machine direction and in cross direction of in each case at least 20% at 93°C, the heat-shrinkability being substantially unaffected by thermoforming, and also to methods whereby the multi-layer film of the invention can be processed advantageously to heat-shrunk packaging, more particularly using specially equipped packaging machines.

La présente invention concerne une feuille multicouche soudable, thermoformable, pouvant rétrécir à la chaleur, qui présente une structure symétrique autour d'une couche intérieure à deux strates et une capacité de rétrécissement à la chaleur dans le sens longitudinal et perpendiculaire d'au moins 20 % à 93 °C respectivement, la capacité de rétrécissement à la chaleur n'étant pas sensiblement influencée par un thermoformage. La présente invention concerne également des procédés selon lesquels la feuille multicouche selon l'invention peut être transformée avantageusement en emballages rétrécis à la chaleur, en particulier en utilisant des machines d'emballage équipées spécialement.
