Cold-formable laminate films, for example for manufacturing push-through or blister packs, or the base parts and for forms of packaging or shaped parts for packaging medical instruments and applicators containing a barrier layer, that is impermeable to water vapour and gases, and a plastic layer on both sides of the barrier layer. The laminate film exhibits a layered structure containing in the following order: a) a plastic layer in the form of a film of the following type viz., polyvinylchloride, polyester, polypropylene, polyamide, cycloolefin-copolymer or a cast film of polyvinyl-chloride or polypropylene, b) a metal foil such as an aluminium foil, and c) an oriented polyamide film having a thickness of 25 to 32 µm The free sides of the first and/or the second plastic film may feature a sealing layer or the first and/or the second plastic films may be sealable. The laminate films may e.g. be processed into forms of packaging by a deepening process such as stretch drawing i.e. by mechanical cold forming using a stamp type tool. During stretch drawing the laminate film is held securely between the die and the holder while the shaping tool forces the laminate into the desired form by stretch forming it.
