PROBLEM TO BE SOLVED: To simply provide a plastic container superior in steam barrier properties at low cost. SOLUTION: This coated container for a beverage or food is manufactured by coating the surface of the plastic container with a composition containing 30-70 mass% of a crystalline higherα-olefin polymer (A) comprising a monomer containing at least one kind of a 18-32Cα-olefin (a1), wherein the melting point is 45-80°C, only one peak temperature is observed and the half value width of the peak temperature is 15°C or below in the measurement of a melting behavior using a differential scanning type calorimeter (a2), 15-45 mass% of an olefinic elastomer (B) with a weight average molecular weight of 2,000-100,000 and 5-30 mass% of petroleum resin (C). The sum total content of the crystalline higherα-olefin polymer (A), the olefinic elastomer (B) and the petroleum resin (C) is 90 mass% or above. COPYRIGHT: (C)2011,JPO&INPIT |
