Abstract
A first laminate which includes a first layer of a phenoxy-type thermoplastic, a second layer of an amorphous thermoplastic copolyester and a third layer of polyethylene terephthalate. A second laminate includes a first layer of a composition of a phenoxy-type thermoplastic and an amorphous thermoplastic copolyester and a second layer of polyethylene terephthalate. Preferably, these laminates are annular with the first layer being the outer ply. Plastic bottle preforms and plastic bottles are commercially important applications of the preferred embodiment wherein an annular laminate is employed.
