| 摘要 |
<p>The present invention relates to a multi-layer heat shrinkable film casing for pasty food, comprising at least an outer layer which includes at least one polyamide based polymer, an inner layer which includes at least one polyamide based polymer and a core layer disposed between the inner layer and the outer layer, the at least one core layer including at least one polyolefin based polymer. The outer layer and the core layer include an amount of a filler composition comprising an amount of at least one carrier material suitable for carrying at least one pigment, the carrier including at least one polymer of an alpha unsaturated aromatic monomer or a copolymer of such a polymer. The vinyl aromatic monomer is preferably styrene. The at least one C3-C10 ±-olefin is preferably butadiene. The carrier material is preferably a thermoplastic styrenebutadiene copolymer, having randomly distributed styrene and butadiene units.</p> |
