PROBLEM TO BE SOLVED: To provide a molded article such as a flexible container or the like enhanced in the heat-resistant creep properties of a welder fusing place and capable of housing a high temperature housing object. SOLUTION: In a tarpaulin 1 becoming a sheet material by laminating resin layers 11 and 12 on both sides of a base cloth 10, the heat-resistant creep properties of the molded article such as the flexible container or the like are enhanced by forming the resin layers 11 and 12 using layers based on a urethane resin in place of a technique for containing methyl methacrylate, ethyl acrylate or the like in a composition, which is prepared by adding a polyolefinic resin to an ethylenic copolymer resin composition used heretofore, to mold the obtained composition into a sheetlike form and integrally joining the molded one to both sides of the base cloth.
