Abstract

L'invention a trait au domaine des matières plastiques. Elle concerne une pellicule formée d'un mélange de copolymère de chlorure de polyvinylidène et d'un copolymère d'éthylène et d'acétate de vinyle contenant environ 5 à environ 18 % en poids d'acétate de vinyle et ayant un écoulement à l'état fondu d'environ 0,1 à environ 1,0 dg/min. Application à la conservation sous emballage, notamment de produits alimentaires.The invention relates to the field of plastics. It relates to a film formed from a blend of polyvinylidene chloride copolymer and ethylene vinyl acetate copolymer containing from about 5 to about 18% by weight of vinyl acetate and having a flow through. melt from about 0.1 to about 1.0 dg / min. Application to the preservation in packaging, in particular of food products.
