Multiple-layer bidirectionally oriented artificial plastic sausage casing of good barrier properties

摘要

Laminated, biaxially oriented tubular film consists of: (a) an inside layer A; (b) a core layer E; (c) an outer layer G of aliphatic (co)polyamide and/or partly aromatic (co)polyamide; (d) a water vapor barrier polyolefin layer C between A and E; which (e) is bonded directly to A and E by adhesion promoting layers B D; and (f) an oxygen barrier layer F between G and E.
