nylon copolymer and nylonblandinger containing this and a - and flerlagsfolier and packaging manufactured accordingly

摘要

The nylon-based composition is a blend or copolymer of nylon 6 and another nylon, e.g. nylon 66 or nylon 12, the latter being 2.5 to 10 mole percent of the overall composition. The blend can be 40 to 70 weight percet nylon 6 and 60 to 25 weight percent of a nylon copolymer which consists of 80 to 90% nylon 6 and 20 to 10% of the other nylon. A packaging film, (10) can have a first layer (18) of the said composition, a second layer )12) of a heat-sealable polymer such as low density polyethylene, a third, gas barrier layer (16) e.g. of ethylene vinyl alcohol copolymer and a fourth layer (14) between the second and third layers, the latter layer for instance being an ethylenic polymer or copolymer. The packaging film can be used for packaging moist products such as meat.
