Title: Layered metal-plastics foil.
IPC: B32B15/04
Filed: 1981-07-30
Abstract: Processes for manufacturing a metal-plastic composite foil having a plastic core covered on both sides with an outer layer of thin metal strip, in particular aluminum thin strip, are already known. However, the use of a so-called triplex composite of the kind just mentioned for relatively large volume containers of full weight up to about 30 kg has been very limited because of the unsatisfactory deep drawing properties of such composites in deep drawing or deep drawing by elongation of the foil (stretching). By means of the invention a process for manufacturing a metal-plastic composite of the so-called triplex composite kind and a metal-plastic composite foil made by this said process have been developed which allow in particular the manufacture of semi-rigid light-weight containers which have a weight of up to about 30 kg when full and this even by cold forming. Containers made from such composite foils are particularly resistant to breakage or leakage and can be closed or fitted together by known sealing methods.
