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 abhesive release layer and at least one layer of a getter material capable of sorbing at least one permeable substance, the getter material being selected from lithium, beryllium, boron, sodium, magnesium, silicon, potassium, calcium, manganese, iron, nickel, zinc, gallium, germanium, cadmium, indium, caesium, barium, boron oxide, calcium oxide, chromium oxide, manganese oxide, iron oxide, copper oxide, silver oxide, indium oxide, barium oxide, lead oxide, phosphorus oxide, sodium hydroxide, potassium hydroxide, metal salts, metal hydrides, anhydrides of single and multiple carboxylic acids, sodium dithionite, carbohydrazide, ascorbates, gallic acid, zeolites, carbon nanotubes, activated carbon and carbodiimides and also mixtures of two or more of the above substances. |
