Multilayered polyamide tube for food packaging
Kuriu and Yabuta of Gunze Limited, Japan, developed a multilayered polyamide-based tube for food packaging that is free from blocking in a Layer (C), with an excellent adherence to processed meat or like packaged food.  This material consists of a Layer (A), a Layer (B) and a Layer (C); the multilayered polyamide-based tube having a low-temperature shrinkage ratio of 2 to 10%, and exhibiting heat shrinkage properties and gas barrier properties; the Layer (A) containing a polyamide-based resin; the Layer (B) containing a polyolefin-based resin; and the Layer (C) that comes in contact with the packaged food, the Layer (C) being a Layer (C-1) that contains a polypropylene-based resin having a heat distortion temperature (ISO 75B-1 or ISO 75B-2) of not less than C. and a Vicat softening point of not less than C., and that has a surface wetting tension of not less than 35 mN/m; or the Layer (C) being a Layer (C-2) that contains a linear low-density polyethylene having a density of not less than 0.92 g/cm.sup.3 but less than 0.95 g/cm.sup.3, and that has a surface wetting tension of not less than 35 mN/m.
