Abstract

La présente invention concerne une feuille adhésive comportant des gaufrages en forme de rhombe ayant différents facteurs de forme et, plus spécifiquement, une feuille adhésive comprenant : un film antiadhésif ayant des formes de rhombe agencées régulièrement dans une forme quadrilatérale dont les quatre côtés sont de longueur égale et les deux diagonales ont des longueurs mutuellement différentes ; et un film adhésif stratifié sur le film antiadhésif. La feuille adhésive comportant des gaufrages en forme de rhombe ayant différents facteurs de forme présente un écart réduit d'allongement longitudinal et transversal et facilite ainsi la dissipation de bulles d'air et réduit le piégeage d'air lorsque le film adhésif est collé à une partie adhérente telle qu'un métal ou un verre.
