FOG-RESISTANT PACKAGING FILM

A packaging film includes a heat sealable layer coated with one or more antifogging agents disposed in a binder, an antiblocking agent, and no more than about 800 ppm slip agent. The heat sealable layer includes a polymer that includes mer units derived from ethylene while the binder includes a poly...

Beschreibung
Zusammenfassung:	A packaging film includes a heat sealable layer coated with one or more antifogging agents disposed in a binder, an antiblocking agent, and no more than about 800 ppm slip agent. The heat sealable layer includes a polymer that includes mer units derived from ethylene while the binder includes a polymer that includes mer units derived from an ester of (meth)acrylic acid and/or vinyl acetate monomers. The antiblocking agent can be in any layer of the film where it provides the desired effect. Such a film, as well as packages made therefrom, can be used to package a variety of products, having particular uility with respect to moist products. L'invention se rapporte à un film d'emballage comportant une couche thermoscellable enrobée d'un ou plusieurs agents anti-buée contenus dans un liant, un agent antiadhérent et une teneur en agent glissant inférieure ou égale à 800 ppm. Cette couche thermoscellable renferme un polymère qui comporte des motifs monomères dérivés de l'éthylène alors que le liant renferme un polymère comportant des motifs monomères dérivés d'un ester d'acide (méth)acrylique et/ou de monomères d'acétate de vinyle. L'agent antiadhérent peut se situer dans n'importe quelle couche du film où il peut avoir l'effet recherché. Un tel film, de même que les emballages réalisés à partir de ce dernier, peuvent être utilisés pour emballer divers produits et, en particulier, des produits humides.
