Multilayer shaped articles, including films, preforms and containers, and
method for forming the same, having at least one layer of
poly(1,3-propylene 2,6-naphthalate) and at least one layer of
poly(ethylene terephthalate). Poly(1,3-propylene 2,6-naphthalate) can be
co-stretched with poly(ethylene terephthalate) to form oriented multilayer
structures which have superior barrier properties. The poly(1,3-propylene
2,6-naphthalate) and poly(ethylene terephthalate) layers have good
adhesion and do not require an adhesive tie layer.
Artigos dados forma multilayer, including películas, pré-formas e recipientes, e método para dar forma ao mesmo, tendo ao menos uma camada de poly(1,3-propylene 2,6-naphthalate) e ao menos uma camada de terephthalate do poly(ethylene). Poly(1,3-propylene 2,6-naphthalate) pode co-ser esticado com terephthalate do poly(ethylene) ao formulário orientou as estruturas multilayer que têm propriedades superiores da barreira. Os poly(1,3-propylene 2,6-naphthalate) e camadas do terephthalate do poly(ethylene) têm a adesão boa e não requerem uma camada adesiva do laço.
