Composicion de resina de revestimiento protector que comprende polietileno de baja densidad, polietileno de muy baja densidad catalizado con metaloceno, un copolimero al azar y un lubricante en donde dicha composicion esta libre de copolimero de vinil acetato de etileno; y un cierre moldeado.

摘要

The invention provides liner resin compositions which are essentially free of ethylene vinyl alcohol (EVA) copolymer and molded plastic closures which include the described liner resin compositions. Instead of EVA copolymers, the provided liner resin compositions generally include low density polyethylene (LDPE). Accordingly, in one embodiment, the invention provides a liner resin composition comprising: a) LDPE; b) metallocene-catalyzed very low density polyethylene; c) a random copolymer; and d) a lubricant; wherein said liner composition is essentially free of EVA copolymer.
