Abstract
(EN)
A thermoplastic film (100) having a substantially continuous adherent coating (110) on at least one surface, wherein the coating includes a polymeric binder and an additive comprising nano-scale particles (112). When the coating is formed on the surface of the film, the nano-scale particles (112) form a barrier that substantially reduces the diffusion of moisture and oxygen. In preferred embodiments, the coating includes a polymeric binder and silicate particles formed on a base substrate layer (120) that includes a polyolefin selected from the group consisting of homopolymers, copolymers and terpolymers of propylene, ethylene and butene and blends thereof.
(FR)
L'invention concerne un film thermoplastique (100) sur au moins une surface duquel se trouve un revêtement adhérant sensiblement en continu (110), dans lequel le revêtement contient un liant polymère et un additif contenant des particules (112) à nanoéchelle. Lorsque le revêtement est formé sur la surface du film, les particules (112) à nanoéchelle forment une barrière réduisant sensiblement la diffusion d'humidité et d'oxygène. Dans les modes de réalisation préférés, le revêtement contient un liant polymère et des particules de silicate formées sur une couche de substrat de base (120) comprenant une polyoléfine choisie dans le groupe contenant des homopolymères, des copolymères ainsi que des terpolymères de propylène, éthylène et butène ainsi que leurs mélanges.
