Abstract

Film et procédé de fabrication d'un film à résistance, à adhésivité à chaud, à rétractibitlié et à possibilités d'extrusion améliorées, destiné à empaquetter et à emballer des aliments, des boissons et des articles non alimentaires. Ledit film amélioré comporte au moins une couche constituée d'au moins un polymère d'éthylène pratiquement linéaire, ledit polymère d'éthylène pratiquement linéaire ayant une répartition de ramification uniforme et étant également caractérisé par le fait qu'il ne possède pratiquement pas de fraction polymère linéaire, qu'il présente un seul point maximal de fusion DSC et une densité supérieure à 0,85 g/cm3. Lesdits films sont utiles dans les opérations d'emballage par rétraction, épousant les formes de l'objet, par extension, ainsi que d'emballage par formage-ensachage-scellage et sous vide.
