Abstract

La présente invention concerne un film thermoplastique comprenant au moins un copolymère d'éthylène soudable par un courant haute fréquence, caractérisé en ce que le film comprend une quantité au plus égale à 0,6% par rapport au film thermoplastique d'au moins un N,N'-éthylène bis amide pour obtenir un temps de soudure haute fréquence au plus égale à 1 seconde. L'invention concerne également un procdé
de soudage à haute fréquence de deux films thermoplastiques.
Les films ainsi soudés sont notamment utilisables pour l'industrie de l'emballage.
