PURPOSE: A multiple layered film for the manufacture of toys is provided to improve a flexibility, high frequency welding property, print ability, air-sealing property of the film so as to be used appropriately in various toys including a beach ball or bag and a tube. CONSTITUTION: In the multiple layered film consisting of a middle layer of polyolefine resin and both outer layers, the middle layer is made of a resin mixture composed of propylene copolymer and ethylene-alphaolefine copolymer, and the both outer layers are made of another resin mixture that propylene copolymer and ethylene-alkylacrylate copolymer are mixed at a ration of 20:80 to 80:20. A density of the resin mixture of the middle layer is 0.870-0.920g/cm3, and a thickness thereof corresponds to 50-90 % of whole thickness.
