Abstract

Un film de polyéthylène stratifié thermo-rétrécissable, parfaitemnt adapté à l'emballage des machines, se compose d'une couche intermédiaire comprenant une composition à base d'un polyéthylène (A) linéaire présentant une faible densité de 0,91 à 0,93 g/cm<3>, un indice de fusion de 0,1 à 0,8 g/10 min, une quantité totale de chaleur de fusion de 135 mJ/mg ou plus, la zone endothermique située au-dessus du point de fusion représentant au moins 12 % de la zone endothermique totale. Ses couches internes et externes comprennent chacune une composition à base de polyéthylène (B) présentant une faible densité faible de 0,91 à 0,93 g/cm<3>, un indice de fusion de 0,8 à 5 g/10 min, et une quantité totale de chaleur de fusion de 135 à 160 mJ/mg, la zone endothermique située au-dessus du point de fusion représentant au moins 12 % de la zone endothermique totale.
