Abstract

See full text

A multilayer film comprising (a) a biaxially-oriented polyethylene furanoate (BO-PEF) polymer layer, (b) an optional ink layer, (c) a bonding layer, and (d) a sealant layer, wherein the BO-PEF polymer has an O2 gas permeability of less than 0.25 cc-mil/100 in.2 24 hrs atm at 80% relative humidity, or a moisture permeability of less than 0.5 g-mil/100 in.2 24 hrs atm at 38° C., or both. The film may be formed from microlayers of BO-PEF-based polymer and polymer with a melting point of at least 5° C. greater than the melting point of the BO-PEF-based polymer.
