    摘要: A laminate has a core layer and a skin layer on either side of the core layer, wherein the skin layer is formed of a copolymer having a glass transition point of 85° C. or more and 115° C. or below and consisting of 2,6-naphthalene dicarboxylic acid or its lower alkyl ester, terephthalic acid or its lower alkyl ester and ethylene glycol or a polymer alloy having a glass transition point of 85° C. or more and 115° C. or below and consisting of polyethylene terephthalate and polyethylene-2,6-naphthalate. Thus, it can be used suitably as a packaging container for food and drink, such as jelly containers, which has flavor resistance and aroma retention sufficient not to be limited by types of flavor used for jelly or the like, excels in sealing properties with a lid body, can be hermetically sealed with an easy-peel transparent lid body, and is also superior in gas barrier properties, impact resistance, heat resistance, cost efficiency and transparency.
