Abstract
(EN)
A multiple-layer composite film comprising: a layer comprising a polymeric base film (12), a barrier layer (13) comprising a carbon-rich material adhered to the base layer, and a heat sealable layer (14) comprising a heat sealable, active gas treated, polymeric material containing ethylene monomeric units adhered to the carbon-rich barrier layer (13).
(FR)
La présente invention concerne un film composite à plusieurs couches. Il se compose d'une couche constituée d'un film support polymère (12), d'une couche barrière (13) constituée d'une matière riche en carbone, adhérant à la couche support, et d'une couche thermo-soudable (14) constituée d'une matière polymère thermo-soudable traitée par gaz actif, laquelle matière polymère contient des unités monomères d'éthylène adhérant à la couche barrière (13) riche en carbone.
