Sterilizible composite film for manufacturing pouch type forms of packaging and the like for e.g. liquid, pasty or solid foodstuffs. The sterilizible composite films according to the present invention contain a barrier layer that is impermeable to water vapor and gases and is in the form of a metal foil. On both sides of the barrier layer is at least one functional layer. The following layers are arranged on top of each other in the composite film: a) a first functional layer containing a plastic film of the polyester or polyolefin type or an extrusion layer of polyolefins or one or more print and lacquer layers or print layers and b) a metal foil and c) a second functional layer in the form of a plastic film of co-extruded polyamide/polypropylene type.
