Lined foil of plastic and metal

摘要

Lined metal-plastic foil exhibits exceptional tensile shearing strength and consists of 0.005-0.5 mm. thick corrosion-resistant metal foil and 0.02-1.0 mm. thick thermoplastic polymerisate foil. The latter is a quaternary polymerisate containing 60-90 wt.% ethylene, 0.5-20.0 wt.% of an ethylenated unsatd. carboxylic acid, 0.5-20.0 of an ester of the latter, as well as 0.3-5.0 wt. % isobutylene.
