JPS6426754A - Cloth for shrink packaging - Google Patents

Abstract

PURPOSE: To obtain a cloth for shrink packaging excellent in mechanical characteristics by laminating polypropylene in an intermediate layer to a linear low-density polyethylene on the outside in a specific weight ratio or providing an outer layer sheath part, drawing the resultant laminate, forming a tape or a fiber and using the tape or fiber as at least either one of a warp yarn or a weft yarn. CONSTITUTION: This cloth for shrink packaging is obtained by arranging polypropylene as an intermediate layer, laminating linear low-density polyethylene having short-chain branches to both outer sides in respective 10-80 wt.% and 90-20 wt.% weight ratios of the intermediate layer and the outer layers, drawing the resultant laminate, forming a drawn tape or arranging the polypropylene in the core part and the linear low-density polyethylene having the short-chain branches in the outer layer sheath part in respective 10-80 wt.% and 90-20 wt.% weight ratios of the core part and the outer layer sheath part, drawing the resultant yarnlike material and forming a drawn fiber and using the tape or fiber as at least either one of a warp yarn and a weft yarn and weaving the cloth. Thereby, the resultant cloth for the shrink packaging is excellent in mechanical characteristics such as impact and abrasion resistances and shrinkable at low temperatures.
