Chlorfreies Verbundfilmmaterial, Verfahren zu seiner Herstellung und sein Gebrauch

摘要

The present invention relates to a chlorine-free multilayer film material comprising a) a gas-barrier layer (1) comprising a non-chlorine containing organic polymer which is substantially impermeable to oxygen gas; b) two tie layers (2) each contacting one side of said barrier layer; c) an inner surface layer (3); d) an outer surface layer (4); and e) two intermediate layers (5) positioned between said surface layers (3,4) and said tie layers (2), said barrier layers (5) comprising an ethylene-propylene copolymer having a flexural modulus of less than 200 MPa and preferably less than 150 MPa, a process for the manufacture of this film material and its use for the manufacture of bags and pouches for ostomy/urostomy use. $$
