MULTILAYER FILM HAVING ACTIVE OXYGEN BARRIER LAYER AND IRON-BASED OXYGEN SCAVENGING LAYER

摘要

This invention is a multilayer having at least one layer containing an active oxygen barrier layer and the iron-based oxygen scavenging composition , relates to a film . In one embodiment , the active barrier layer , (A) substantially in a main chain of carbon - oxygen scavenging composition comprises a blend of a thermoplastic resin having carbon-carbon double bond , (B) a transition metal salt and (C) an oxygen barrier polymer The . In some embodiments , the active barrier layer may also include a compatibilizer (D). Layer containing an iron-based oxygen scavenging composition wherein , retort and non- retort under all conditions , helps to maintain the oxygen barrier properties of the active barrier layer . As a result, the useful shelf life of the multi-layer film can be extended. ;
