Protective film for sheet metal strips or straps

摘要

The protective film is used for covering a piece of sheet metal especially used as part of a walkway. It comprises a surface with a frictional coefficient of at least 0.6, especially 0.8 or more. The surface preferably has a lacquer coating based on aliphatic polyamides. The protective film is preferably made of a polyamide material. The film may especially consist of a comparatively thick layer of polyethylene (1) with a layer of adhesive (2) on its underside and an imprinted or patterned layer (3) on its top carrying the lacquer layer (4).
