CA 2431542

An insulated beverage or food container or sleeve is produced with a foam layer disposed on an inner surface of a paper stock. A polymer shrink film layer is arranged in a position along an inside surface of the beverage container. The foam layer is sandwiched between the polymer shrink film layer and the paper stock and decreases the energy transfer between the beverage and the user's hands allowing the user to hold onto the container for an extended period of time without causing user discomfort or pain. The polymer shrink film layer is produced from a shrink film polymer having a percent shrink in the range of 30% or less, and more particularly a percent shrink range of 5 to 10%.

L'invention concerne un manchon ou un récipient isolé pour boissons ou pour aliments produit à l'aide d'une couche de mousse disposée sur la surface intérieure d'une masse de papier. Une couche de film polymère rétractable est agencée dans une position longeant la surface intérieure du récipient à boissons. La couche de mousse est prise en sandwich entre la couche de film polymère rétractable et la masse de papier et réduit le transfert d'énergie entre la boisson et les mains d'un utilisateur, ce qui lui permet de tenir ledit récipient pendant une durée prolongée sans ressentir de sensation gênante ou de douleur. La couche de film polymère rétractable est produite à partir d'un polymère de film rétractable dont le pourcentage de rétrécissement se situe dans une plage de 30 % ou moins, et plus particulièrement dans une plage comprise entre 5 et 10 %.
