HIGH BARRIER MULTILAYER FILM

摘要

The present invention is a high barrier multilayer film particularly suitable for packaging. The high barrier multilayer film is a film including (a) a core substrate layer having an isotactic polypropylene produced from Ziegler-Natta catalysts, and (b) an adjacent layer on at least one surface of the core substrate layer, wherein the adjacent layer (b) comprises an isotactic polypropylene produced from metallocene catalysts; or the high barrier multilayer film includes (a') a core substrate layer having an isotactic polypropylene produced from metallocene catalysts, and (b') an adjacent layer on at east one surface of the core substrate layer, wherein the adjacent layer (b') comprises an isotactic polypropylene produced from Ziegler-Natta catalysts.
