SETT OCH ANORDNING FOR FRAMSTELLNING AV SKALFORMIGA BEHALLARE AV EN PLAN METALL-PLASTLAMINATFOLIE

摘要

The invention concerns a process and a device for manufacturing blisters with high barrier properties from a metal-plastic composite foil which can be deep drawn, in particular from an aluminum-plastic composite foil which is held fast in the clamping facility of a device for manufacturing blisters. In shaping the foil into one or more blisters, pressure is applied pneumatically or pneumatically and hydraulically to at least one side of the foil which stretches onto and over a lubricating layer or easy slip plate on the base of a die.
