VERPACKUNGSFOLIE, INSBESONDERE WURSTHUELLE, AUF BASIS VON POLYAMID |
摘要 |
The cylindrical, biaxially stretch-oriented packaging film, particularly synthetic sausage casing, is composed of a polymer mixture of… (a) 65 to 85% by weight of aliphatic polyamide,… (b) 7 to 15% by weight of polyterephthalate,… (c) 4 to 19% by weight of aromatic polyamide, built up from units of branched aliphatic diamines having at least 7 C atoms and aromatic dicarboxylic acids, particularly terephthalic acid and/or isophthalic acid, or from units of aromatic diamines, particularly xylylenediamine, and aliphatic dicarboxylic acids having 5 to 11 C atoms, particularly adipic acid, and… (d) 0.5 to 10% by weight of dye. …<??>The weight proportion of the aromatic polyamide is preferably the same as, particularly greater than, the weight proportion of the dye. A master batch for production of the film is also described. The film having this composition can particularly advantageously be dyed deep black or brilliant red. |
