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.

摘要： A resin composition (E) includes from 0.1 to 20 parts by mass of an ethylene-vinyl alcohol copolymer (B), from 0.1 to 20 parts by mass of an acid-modified polyolefin (C), and from 0.1 to 10 parts by mass of an acid-modified polyolefin (D) based on 100 parts by mass of a polyolefin (A), wherein the polyolefin (A) has an MFR (190°C, under a load of 2.16 kg) from 0.01 to 10 g/10 min, the acid-modified polyolefin (C) has an acid value from 0.1 to 9 mg KOH/g, the acid-modified polyolefin (D) has an acid value of more than 10 mg KOH/g and 120 mg KOH/g or less, and a ratio (D/A) of an MFR (190°C, under a load of 2.16 kg) of the acid-modified polyolefin (D) to the MFR (190°C, under a load of 2.16 kg) of the polyolefin (A) is 50 or more. The resin composition (E) of the present invention causes reduction in the amount of deteriorated materials adhering to a screw and/or a die even when long-term continuous melt molding is conducted. Use of the resin composition (E) also allows production of a molded article exhibiting excellent impact resistance and appearance. The production method of the present invention allows long-term stable production of the resin composition (E).
