Komplementärer Profilverschlussstreifen und Beutel mit demselben

摘要

Each of bases for fusing a snap-zipper male member and a snap-zipper female member, comprising of a snap zipper, onto a bag body is formed from a mixture of polypropylene and an ethylene copolymer obtained by copolymerizing ethylene and alpha -olefin having a carbon atom ratio of 3 to 20, in which the ethylene copolymer has a weight average molecular weight/number average molecular weight of less than 3, the density of a range from 0.850 g/cm<3> to 0.935 g/cm<3>, a melt index of a range from 0.3 g/10min, to 15 g/10min., and the range of the number of branching dependent on molecular weight of 0-5 branches/1,000 carbon. A bag with the snap zipper is structured to fuse the snap zipper through the bases onto the bag body.
