Abstract

L'INVENTION CONCERNE UN FILM PLASTIQUE COMPOSE DE TROIS COUCHES, LA COUCHE INTERNE ETANT EN POLYETHYLENE HAUTE DENSITE BASSE PRESSION. SELON L'INVENTION, LE FILM EST RENDU TRANSPARENT ETOU BRILLANT DANS SON ENSEMBLE, MALGRE SON AME MATE ET OPAQUE, EN PRENANT POUR LES COUCHES EXTERIEURES DES FILMS TRANSPARENTS ETOU BRILLANTS. CES COUCHES EXTERIEURES SONT CONSTITUEES PAR DES POLYOLEFINES (POLYETHYLENE BASSE DENSITE, POLYETHYLENE GREFFE, ETHYL VINYL ACETATE, ETC.) ET PEUVENT ETRE DIFFERENTES L'UNE DE L'AUTRE. TRES AVANTAGEUSEMENT, LE FILM COMPLEXE EST REALISE PAR LA CO-EXTRUSION DES TROIS COUCHES. LES FILMS SELON L'INVENTION PERMETTENT DE BONNES PERFORMANCES MECANIQUES ET SONT UTILISES POUR LE CONDITIONNEMENT SOUPLE SOUS TOUTES SES FORMES, Y COMPRIS LE PELLIPLACAGE.
