Abstract

In the case of a liner for the protection of adhesives, the protective effect is to be enhanced in respect of permeates originating from the environment and also permeates included during winding or stacking and other processing steps. This enhancement is accomplished through provision of a liner which comprises at least one adhesive release layer and at least one layer of a getter material capable of sorbing at least one permeable substance.
