<p>PURPOSE:To obtain a fuel vessel having permeation preventive properties of gasoline, gas holes, impact resistance and stress crack resistance by specifying a mixing ratio of 6/12 nylon copolymer mixed with ethylene-vinyl alcohol copolymer for forming a resin layer and 6-nylon component and 12-nylon component copolymerization ratio. CONSTITUTION:A fuel vessel has a resin composition layer containing 50-90wt.% of ethylene vinyl alcohol copolymer A and 10-50wt.% of 6/12 nylon copolymer B. The copolymer B has a 6-nylon ingredient and 12-nylon ingredient copolymerization ratio for satisfying 85/15<=6-nylon ingredient/12-nylon ingredient : 55/45. The layer may include the 6-nylon copolymer C. In this case, it satisfies 10/90<=(B+C)/A<=50/50 and 70/30<=B/C<=95/5.</p> |
