Abstract
A film is provided that has three layers. The inventive films are made of semicrystalline or amorphous copolyesters and further include two exterior layers and an interior layer. The exterior layers include neopentyl-glycol-modified polyethylene terephthalate, while the interior layer includes 1,4-cyclohexanedimethanol-modified polyethylene terephthalate. The inventive films advantageously provide a shrink film that has a shrink performance similar to that of shrink films made of PVC.
