description	Coextruded, unstructured, transparent and thermoformable polyester films are provided including at least one base layer (B) made of a-PET and one heat-sealable outer layer (A). The heat-sealable outer layer (A) includes at least 80% by weight of polyester with from 25 to 95 mol % of units derived from at least one aromatic dicarboxylic acid and 5 to 75 mol % of units derived from at least one aliphatic dicarboxylic acid, along with aliphatic diols. The outer layer (A) also includes up to 0.4% by weight of inorganic or organic particles with median diameter d50 2.0 to 8.0 μm. The thickness of the outer layer (A) is 10 to 100 μm, and the thickness of the film is in the range 100 to 1500 μm. The invention further relates to processes for producing the inventive film, and also to packaging for foods or other consumable products, such as trays.
