"smoke and water vapor permeable food enclosure with optimized adhesive properties". The present invention relates to a seamless, vapor-permeable, smokeable, biaxially stretch oriented and partially or completely thermosetted tubular food shell having at least two layers based on thermoplastic polymers. at least one layer a, which does not form the inner layer, comprises a mixture of aliphatic (co-) polyamide and at least one hydrophilic polymer, while inner layer i comprises a mixture of aliphatic or isocyclic (co-) polyamide and a copolymer in block, selected from polyether amide, polyether ester and polyether urethane. The housing is produced by a pipe blowing process or by a biaxial pipe stretching process. the wrapper is provided in particular as artificial sausage wrapper, especially for raw smoked sausage such as salami.
