摘要： To provide a resin composition, a pellet, a composite molded article, a method for manufacturing a composite molded article and a tank, all capable of enabling tight joining and integration of the polyacetal resin molded article and the polyethylene resin molded article, and of suppressing formaldehyde emission and occurrence of mold deposit. The resin composition contains a resin ingredient and melamine, the resin ingredient containing a polyacetal resin and a maleic anhydride-modified polyethylene resin, the polyacetal resin and the maleic anhydride-modified polyethylene resin following a mass proportion of (20 to 49):(80 to 51), and molar concentration of the maleic anhydride group capable of reacting with amino group of melamine contained in the resin composition being 5 to 25 µmol/g.

摘要： A polyethylene based resin exhibiting excellent moldability and durability and having an excellent balance between impact resistance and stiffness; and a hollow plastic molded article using the foregoing resin, which exhibits excellent moldability, durability and barrier properties and has an excellent balance between impact resistance and stiffness, are provided. The polyethylene based resin satisfies the following requirements (1) to (4): (1) a high-load melt flow rate (HLMFR) is from 1 to 100 g/10 min; (2) a density is from 0.940 to 0.960 g/cm 3 ; (3) a strain hardening parameter λmax of elongational viscosity is from 1.05 to 1.50; and (4) a rupture time in a full notch tensile creep test and a density satisfy the following relational expression (A): log (rupture time) ≥ -355 × (density) + 337.6 (A).
