Multilayer film structure comprising renewably sourced materials |
摘要 |
A coextruded multilayer structure which can be oriented and a process therefor are disclosed in which the structure comprises a poly(hydroxyalkanoic acid) polymer (PHA) composition layer, a tie layer, and a sealant layer and the process comprises, consists essentially of, or consists of coextruding a PHA composition, a tie layer composition, and a sealant layer composition to produce a tubular multiplayer structure; cooling the multilayer film structure in a first bubble to produce a tubular multilayer structure; orienting the tubular multilayer structure under heating in a second bubble to produce an oriented tubular multilayer structure; and relaxing the oriented tubular multilayer structure under heating in a third bubble. The structure can be used to produce an article such as a packaging article. |
