Abstract

L'invention concerne un procédé de fabrication d'un film d'emballage destiné au guipage, caractérisé en ce qu'il consiste à extruder un mélange comportant de 90 % à 99,5 % en poids de polyéthylène et de 0,5 % à 10 % en poids de polyisobutylène pour former un film, puis traiter une face du film à l'aide d'un décharge corona. De préférence, le pourcentage en poids de polyisobutylène sera compris entre 3 et 4,5 %. Application : emballages.
