Single layer tubular casing comprising mixt. of polyamide-6 - and co-polyamide from hexa:methylene di:amine, terephthalic acid and isophthalic acid, esp. sausage skin

摘要

A single layer tubular casing, stretch-oriented biaxially and heat-fixed, comprises a mixt. of (a) polyamide 6 and (b) an aromatic copolyamide from hexamethylene diamine, terephthalic acid and isophthalic acid. The mixt. contains 10-90 (10-30) wt.% of the aromatic copolyamide, the rest being polyamide 6. USE/ADVANTAGE - The casing is an artificial sausage skin (claimed). The casing has a natural glass-clear appearance, and adequate elastic recovery (i.e. it adapts to the sausage compsn. after boiling or cooking and cooling). It adheres to the sausage compsn. and prevents the entry of liquids.
