Handfüllbare Wursthülle auf Polyamidbasis

摘要

The invention concerns a biaxially stretched and thermofixed tubular seamless single- or multi-layered foodstuff skin wherein the layer, or, in the case of multi-layered skins at least one of the layers, contains a block copolymer with "hard" aliphatic polyamide blocks and "soft" aliphatic polyether blocks, the block copolymer corresponding to one of formulae (I) to (III), Ea-(NH-[CH2]x-CO)m-Xa-(A-O)n-A-Xa-(CO-[CH2]x-NH)m-Ea (I), (II), -[X-(CO-[CH2]x-NH)o-Y-X-(A-O)p-A]- (III). The invention is particularly suitable as a skin for sausages which are to be boiled or heated in water, and does not form folds when the filling is introduced manually, that is with no or only slight pressure, i.e. without using special filling machines.
