ARTICLES HAVING A FLEXIBLE GAS BARRIER LAYER |
摘要 |
The plastic articles comprise at least two layers. The first layer (1) is an oxygen permeable plastic material. The second layer comprises (A) from 65 to 95 weight percent of a thermoplastic vinylidene chloride copolymer and (B) from 35 to 5 weight percent of a thermoplastic halogenated polymer of one or more types of non-aromatic ethylenically unsaturated hydrocarbons of 2 to 12 carbon atoms, based on the total weight of (A) and (B). The two layers can be coextruded for producing the plastic articles. Alternatively, a base plastic article which comprises the first layer (1) can be coated or laminated with the second layer (2). The plastic articles have excellent gas in particular oxygen barrier properties. |
