Patent ID: 8092883

Claim:
A resin tank weld member that is welded to a resin tank, the resin tank weld member being solely a single layer comprised of a polyamide/polyolefin-based resin composition obtained from: 100 mass parts of a polyamide resin composition in which 2 to 20 mass parts of a silicate layer of a swellable lamellar silicate is dispersed at a molecular level with respect to 100 mass parts of a polyamide resin, a relative viscosity of the polyamide resin composition measured with a solvent of a 96 mass% concentrated sulfuric acid in a condition of a temperature being 25° C. and a concentration being 1 g/dl is greater than or equal to 2.0, and an amino-terminal group content of the polyamide resin composition is less than or equal to 0.07 mmol/g, and 50 to 150 mass parts of a polyolefin-based resin composition obtained by modifying 1.0 to 4.0 mass parts per 100 mass parts of a polyolefin-based resin having a density that is greater than or equal to 0.92 g/cm 3 with an α,β-unsaturated carboxylic acid or an acid anhydride.
