Abstract

L'invention concerne un film mince universel facile à arracher, qui comprend de haut en bas une couche de film facile à arracher, une couche adhésive et une couche superficielle interne en séquence. La couche de film facile à arracher est un film BOPE, la couche superficielle interne est un film VMPE, et une face supérieure de la couche de film facile à arracher est munie de multiples évidements. Un procédé de traitement du film mince universel facile à arracher comprend les étapes consistant à : a) presser de multiples évidements sur une face supérieure d'une couche de film facile à arracher ; et b) combiner une face inférieure de la couche de film facile à arracher avec une couche superficielle interne. Une chaîne de production associée comprend, en séquence, un premier mécanisme de déroulement, un second mécanisme de déroulement, un mécanisme de combinaison et un mécanisme d'enroulement, un mécanisme de formation d'évidements étant implanté entre le premier mécanisme de déroulement et le mécanisme de combinaison. Comme les multiples évidements sont formés sur la face supérieure de la couche de film facile à arracher, le film mince universel facile à arracher peut être facilement arraché dans n'importe quel sens par un utilisateur. Étant donné que la couche de film facile à arracher est un film BOPE et que la couche superficielle interne est un film VMPE, le film mince universel facile à arracher peut être recyclé et réutilisé après utilisation, ce qui réduit considérablement l'impact défavorable sur l'environnement.
