Abstract:
Provided is a fuel container composed of a multilayer structure containing: an ethylene-vinyl alcohol copolymer (A) layer; an adhesive resin (B) layer; a high-density polyethylene (C) layer; and a resin composition (D) layer, wherein the ethylene-vinyl alcohol copolymer (A) contains 15 to 44 mol % of ethylene, the adhesive resin (B) is a maleic anhydride-modified polyolefin having an acid value of 0.1 to 10 mgKOH/g and containing 1 to 8.5 μmol/g of magnesium element, calcium element, zinc element, or a combination thereof, the resin composition (D) contains the ethylene-vinyl alcohol copolymer (A), the adhesive resin (B), and the high-density polyethylene (C), the thickness of the (A) layer, the (B) layer, and the (C) layer satisfies specific conditions, and the ethylene-vinyl alcohol copolymer (A), the adhesive resin (B), and the high-density polyethylene (C) satisfies specific conditions. The fuel container is excellent in fuel barrier properties and impact resistance and enables stable production.
