A bag with a snap zipper according to the present invention has a bag body produced to cause the snap zipper to fuse via a portion for fusion to the bag body to a layer composed of a polyester type resin on the bag body. In the present invention, at least a portion in the snap zipper to be fused to the bag body is made of a material mainly composed of a polyester type elastomer or a polybutylene terephthalate (PBT) resin and that the resin of the portion for fusion has a bending modulus of elasticity of 10,000 kg/cm.sup.2 or below. At least its portion for fusion is made of a material having a composition including polyester type elastomer and a polyolefin type resin or polybutylene terephthalate (PBT) resin and a polyolefin type resin and that the content of the polyolefin type resin in the composition is 3 to 50% by weight. When the snap zipper is adapted to have a portion for fusing to the bag body and the male and female members, except the portion for fusion, the portion for fusion may be composed of a copolymer of ethylene and acrylic acid ester or a copolymer of ethylene and methacrylic acid ester.
