摘要

A smokeable flat or tubular sheath or film (I) for foodstuff packaging, particularly sausage skins or shrink wrap is polymer based comprising a homogeneous polymer melt or mixture comprising 40-80 wt.% polyamide (PA), 5-40 wt.% polyvinyl alcohol (PVAC) and 20-30 wt.% polyether block amide (PEBAX) whereby the film or sheath is formed by blow molding. An independent claim is included for a process for the production of the sheath or film (I) by filling of the film or sheath (I) with sausage or meat product prior to smoking.
