Abstract

L'invention concerne un sac, notamment biodégradable et/ou compostable, comprenant un film comportant au moins une première couche de papier, notamment de papier kraft, présentant une face intérieure et une face extérieure. Une composition hydrophobe est enduite sur au moins une partie de la face extérieure de la première couche de manière à ce que la partie de la face extérieure enduite présente une tension de surface avec l'air inférieure ou égale à la tension de surface avec l'eau. L'invention concerne également un procédé de fabrication d'un tel sac.
