The present invention relates to a transparent peelable polyester film comprising a biaxially oriented polyester film (B) having first and second surfaces, another layer (C) applied to the first surface of the base layer (B), and one on the second surface thereof Base layer (B) applied heat-sealable and peelable over APET and RPET menu shells cover layer (A), wherein the heat-sealable and peelable cover layer (A) represents an off-line coating and offn(a) 85-99% by weight of polyester andn(b) 1 - 15 wt .-% of other substances, whereinnthe polyester is made up of 25-95 mole percent of units based on at least one aromatic dicarboxylic acid and 5-75 mole percent of units derived from at least one aliphatic dicarboxylic acid, the sum of the dicarboxylic acid derived mole percent being 100 andnthe polyester is composed of at least 10 mol% of units derived from linear or branched diols having greater than 2 C atoms, wherein the sum of the diol components gives 100 mole percent andnthe layer (C) comprises crosslinked acrylate and / or methacrylate-based copolymers. The invention further relates to a production process for this peelable polyester film and its use as a sealing film for APET and / or RPET menu trays. |
