PROBLEM TO BE SOLVED: To provide a flexible and shape retainable plastic molded product able to be used like a metal-made product. SOLUTION: The plastic molded product is produced by extruding and molding a resin composition comprising at least 3 components of a polyester, a polyolefin and a polyfunctional modified vinyl polymer and rolling the extruded product to have≤80% thickness. The plastic product is also produced by preparing a resin by blending 100 pts.wt. biodegradable polyester resin (flexible plastic group) having 50-1,000% elongation in tensile characteristics with 25-400 pts.wt. biodegradable polyester (brittle plastic group) having 1-30% elongation in tensile characteristics, extruding the resin containing the aforesaid resins as main components and rolling the extruded resin to have≤80% thickness.
