Zusammenfassung:A transparent peelable polyester film is provided having a base layer (B) with first and second surfaces. A layer (C) is applied on the base layer (B). A heat-sealable layer (A), peelable to APET AND RPET, is applied on the opposing surface of the base layer (B). The heat-sealable and peelable outer layer (A) is formed from(a) from 85 to 99% by weight of polyester and(b) from 1 to 15% by weight of other substances. The polyester is formed from 25 to 95 mol % of units derived from at least one aromatic dicarboxylic acid and from 5 to 75 mol % of units derived from at least one aliphatic dicarboxylic acid, and the polyester includes at least 10 mol % of units derived from linear or branched diols having more than 2 and the layer (C) includes crosslinked acrylate and/or methacrylate-based copolymers.
