PROBLEM TO BE SOLVED: To provide a cloth sheet, which is light in weight, has a high strength, is excellent in flexibility, and has a high frequency weldability. SOLUTION: This cloth sheet is produced by forming coating layers on both sides of a cloth woven or knitted of stretched polypropylene yarns. The coating layer consists of a layer made of a component A and a layer made of a component B. The component A is a pluralistic copolymer consisting of an ethylene and a radical polymerizable acid anhydride and a radical polymerizable comonomer except them under the condition that the percentage of an aicd anhydride group containing unit is 0.1-5 wt.% and the percentage of an ethylene unit and the unit except the acid anhydride group containing unit is 3-50 wt.%. The component B has a crystalline propylene-based polymer portion (a), an ethylene-containing copolymer portion (b), which is insoluble in a xylene under room temperature, and an ethylene-containing copolymer portion (c), which is soluble in the xylene under room temperature. |
