METHOD FOR INCREASING THE ADHESIVE POWER OF A PRESSURE-SENSITIVE ADHESIVE LAYER HAVING AN UPPER AND A LOWER SURFACE

摘要

Method for increasing the adhesive power of a pressure-sensitive adhesive layer having an upper and a lower surface, wherein at least one surface of the pressure-sensitive adhesive layer is subjected to a physical process, said physical process being selected from among the group comprising corona discharge, dielectric barrier discharge, preliminary flame treatment, or plasma treatment.
