Abstract
A polymer blend disclosed has a coherent phase made from an aliphatic and/or semiaromatic (co)polyamide and, dispersed therein, a phase made from an olefin block copolymer grafted with intramolecular carboxylic anhydrides. The olefin block copolymer preferably comprises PP blocks and EPM blocks, and, where appropriate, also EBM blocks. A flat or tubular film is also disclosed wherein at least one layer thereof comprises the polymer blend. The film has preferably been mono- or biaxially oriented, and, where appropriate, also heat-set. A tubular film of the present invention is particularly suitable as a synthetic casing for sausages.
