Adhesion-promoted , heatsealable and peelable polyester film, process for its production and its use |
摘要 |
Coextruded, biaxially oriented polyester films which have a base layer (B) and have a heatsealable outer layer (A) that can be peeled from APET/CPET and from CPET, where the outer layer (A) includes a) from 60 to 99% by weight of polyester and b) from 1 to 10% by weight of inorganic and/or organic particles with a median diameter d<SUB>50 </SUB>of from 2 to 8 mum, and where c) the polyester is composed of from 12 to 89 mol % of units derived from at least one aromatic dicarboxylic acid and of from 11 to 88 mol % of units derived from at least one aliphatic dicarboxylic acid, and the non-sealable surface of the film has been rendered adhesion-promoting. The films of the invention are suitable as a packaging material for foods and other consumable items, and as a lid film for APET/CPET or CPET trays.
