摘要

The film web comprises at least two layers, is composed of at least one plastic film web or paper web and has an overall thickness of 50 - 500 mu m and a 3 - 30 mu m acrylate coating arranged directly thereon or arranged on an intermediate layer or intermediate plastic layer attached thereto, and prepared in the presence of at least one monomeric, dimeric and/or trimeric acrylate and at least one prepolymeric acrylate. The radiation-curable coating contains or comprises 20 - 60 parts by weight of a matting agent (flatting agent) or matting agent mixture, 1 - 10 parts by weight of a UV initiator or UV initiator mixture, and 0 - 10 parts by weight of a blowing agent or blowing agent mixture per 100 parts by weight of the acrylate coating (calculated without each additive, processing assistant or blowing agent).
