PURPOSE:To provide a thermoplastic resin composition excellent in flexibility, toughness and low-temperature characteristics, giving excellent high-frequency weldability in mutually welding films or sheets using a high-frequency sewing machine or high-frequency welding machine. CONSTITUTION:The objective mixed resin composition comprising (A) an ethylene-vinyl acetate copolymer containing 5-15wt.% of vinyl acetate constituent and (B) a vinyl chloride-based resin composition consisting mainly of a vinyl chloride-based graft copolymer produced by graft polymerization of (1) 70-50wt.% of vinyl chloride to (2) 30-50wt.% of an ethylene-vinyl acetate copolymer containing 20-45wt.% of vinyl acetate constituent in the weight ratio A/B of (40:60 to (95:5).
