摘要

A composite material capable of being deep-drawn or stretch-formed is claimed (I), contg. a metallic layer 8-80 microns thick (A) between two layers of plastic each 20-50 microns thick (B) consisting of or contg. polyamide-based thermoplastic (II). Also claimed are deep-drawn or stretch-formed containers made of (I) as described above. Layer (A) is a foil or thin strip of Al or Al alloy, 40-70 microns thick. Layers (B) are based on polycaprolactam or a copolymer thereof, pref. biaxially oriented and with a sealing layer on at least one side. Layers (B) are each 20-50 (pref. 20-30) microns thick, and the difference in thickness of these layers if 0-20%.
