Biaxially oriented polypropylene film with low moisture vapor transmission rate

摘要

A laminate film comprising a core layer comprising of a high crystalline propylene homopolymer blended with an amount of hydrocarbon resin; crystalline polyethylene wax; and a fluoropolymer and/or a metal oxide nanoparticle which exhibits excellent transparency and moisture vapor barrier properties. The laminate film could further have additional layers such as a second polyolefin resin-containing layer, or a heat-sealable polyolefin-containing layer, or combinations thereof.
