发明名称 Multilayer structures of poly(1,3-propylene 2,6 napthalate) and poly (ethylene terephthalate)
摘要 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.
