Beschreibung
Zusammenfassung:	The present invention relates to a thermoformable composite film comprising at least one film which comprises cycloolefin copolymer and comprising, laminated to at least one side of this film, a thermoplastic film. The thermoformable film is obtainable by using a solvent-free single-- component adhesive to apply the thermoplastic film laminated to the film which comprises cycloolefin copolymer. The film which is laminated is a PVDC-containing thermoplastic film. The thickness of the entire film is from 100 to 500 pm, the thickness of the PVDC film is from 5 to 150 pm and the thickness of the COC film is from 50 to 400 .mu.m. The thermoformable composite film is used to produce blister packs.
