A halogen-free winding tape composed of an at least two-layer film and, preferably, of an adhesive layer applied thereto, characterized in that the film comprises A) a first layer containing a copolymer of (a) an alpha-olefin of the formula R-CH-CH<SUB>2</SUB>, where R is hydrogen or an alkyl radical having 1 to 10 carbon atoms, and (b) an alpha,beta-ethylenically unsaturated carboxylic acid of 3 to 8 carbon atoms, and (c) optionally a further monoethylenically unsaturated monomer, 10 to 90% of the carboxylic acid groups of the copolymer being substituted by metal ions as a result of neutralization, and B) at least one further, second layer of an ethylene polymer having a melt index of less than 8 g/10 min at 2.16 kg and 190° C.
