摘要:
There is provided a fuel container comprising a layer made of a resin composition (E) comprising polyethylene (A), EVOH (B), acid-modified polyethylene (C) and acid-modified polyethylene (D), wherein the resin composition (E) contains 0.1 to 20 parts by mass of EVOH (B), 0.1 to 20 parts by mass of acid-modified polyethylene (C) and 0.1 to 10 parts by mass of acid-modified polyethylene (D) based on 100 parts by mass of polyethylene (A); an MFR (190 °C, under 2.16 kg load) of the polyethylene (A) is 0.01 to 10 g/10 min; an acid value of the acid-modified polyethylene (C) is 0.1 to 9 mg KOH/g; an acid value of the acid-modified polyethylene (D) is more than 10 mg KOH/g and 120 mg KOH/g or less; and a ratio (D/A) of an MFR (190 °C, under 2.16 kg load) of the acid-modified polyethylene (D) to an MFR (190 °C, under 2.16 kg load) of the polyethylene (A) is 50 or more. For a fuel container of the present invention, the amount of deteriorated materials adhering to a screw and/or a die is reduced even when long-term continuous melt molding is conducted during production thereof, resulting in higher productivity. Furthermore, the fuel container exhibits excellent impact resistance with less stripes being generated.
