Abstract (en)
[origin: EP0597650A1] A snap zipper (11), in which at least a portion to be fused is mainly composed of a polyolefin type adhesive resin. The polyolefin type adhesive resin has a structure obtained as a result of partial grafting of unsaturated carboxylic acid to a mixture of one or more polyolefin varieties. At least a portion to be fused is mainly composed of polyethylene terephthalate (PBT) resin or polyester type elastomer, the resin in the portion to be fused having a bending modulus of elasticity of 10,000 kg/cm<2> or below. At least a portion to be fused is mainly composed of polyester type elastomer or polybutylene terephthalate resin and polyolefin type resin, the composition containing 3 to 50 % by weight of the polyolefin type resin. A bag (24) with snap zipper (11), in which the snap zipper (11) according to either of the first to third aspects of the invention noted above is fused via the portion for fusion to a bag body (22). The snap zipper (11) according to the first to third aspects of the invention permits use of the polyester type resin for the bag body sealant layer, to which the snap zipper (11) is fused. <IMAGE>
