    • PROBLEM TO BE SOLVED: To provide a coated base fabric for airbags including: a cloth obtained by weaving polyamide (PA) fiber yarns; and a PA elastomer coating film formed on one surface or both surfaces of the cloth, wherein the coated base fabric has predetermined air tightness and flexibility, is easily converted to a PA reproduced material. SOLUTION: The coated base fabric for airbags is obtained by fusing a coating film 16 made of an airflow suppression PA elastomer on one surface or both surfaces of a cloth 14 obtained by weaving yarns 12 and 12A made of a polyamide (PA) fiber. As the PA elastomer, soft PA is normally used, which has a melting point (measured by the standard of ASTM D3418) of 135 to 200°C, a difference between the melting points of the PA fiber and PA elastomer being 80 to 120°C.
