<p>PURPOSE: To provide a laminate capable of being used in producing a recyclable bottle holding a small vol. of a carbonate beverage, constituted of a first layer of a phenoxy type thermoplastic resin, a second layer of an amorphous thermoplastic copolyester and a third layer of polyethylene terephthalate. CONSTITUTION: A cylinder 7 of a three-layered laminate includes a first outer layer 130 comprising a phenoxy type thermoplastic resin, a second intermediate layer 140 bonded to the layer 130 and containing an amorphous copolyester resin, and a third inner layer 150 comprising a polyethylene terephthalate resin. As the phenoxy thermoplastic resin, there are poly(hydroxy ether), poly(hydroxy ester ether) and poly(hydroxyamino ether) having a high degree of polymn. As the amorphous thermoplastic copolyester resin, there is poly(1,4- cyclohexylmethylene) terephthalate-co-isophthalate.</p> |
