Abstract
A snap-zipper 10 comprises a male and a female member 11 and 12 having strip-like bases 21 and 22 for fusion bonding, the bases being made of an ethylene.multidot..alpha.-olefin copolymer with a MI of 0.3 to 15 g per 10 min., a density of 0.850 to 0.935 g/ml, a molecular weight distribution of 2 to 5, a molecular-weight-dependent width of branch number of 0 to 5 per 1,000 carbon atoms, an olthodichloroenzene soluble component content of 10% by weight or below, and a maximum melting point determined with a differential scan calorimeter of 115.degree. C. or below. A bag 30 with a snap-zipper is obtained by fusion bonding the stems 21 and 25 of the snap-zipper 10 to a bag body 31.
