Laminated plastic and metal sheet for - packing and insulation

摘要

The laminated sheet has two 0.01-1 mm. thick outer thermoplastic polymer layers and an intermediate 0.005-0.5 mm. thick metal layer. The outer layers are a quaternary polymer, which comprises (pbw): 60-90 ethylene, 0.5-20 ethylene unsatd. carboxylic acid, 0.5-20 ethylene unsatd. carboxylic acid ester and 0.3-5 isobutylene, so that the parts total 100 in a polymer bound form.
