<p>Laminates having a core layer and skin layers in both sides of the core layer, wherein the skin layer is made of a copolymer of 2,6-naphthalenedicarboxylic acid or its lower alkyl ester with terephthalic acid or its lower alkyl ester and ethylene glycol having a glass transition point of from 85 to 115°C, or a polymer alloy of PET with polyethylene-2,6-napthalate having the glass transition point as defined above. Because of excellent in the resistance to various flavors, sealing properties with easy-peeling transparent covers, gas-barrier properties, impact resistance, heat resistance, economical efficiency and transparency, the above laminates are suitable for containers of foods and drinks such as jelly containers.</p> |
