摘要
A co-extruded microlayered polymer barrier film is provided. The barrier film can be applied to paperboard to form a container having reduced oxygen gas permeability. Co-extrusion of the barrier film allows for the simultaneous fabrication of tens or hundreds of alternating microlayers of two different polymers that combine to form a film having reduced oxygen gas permeability compared to macro layer thickness films of the same two polymers.
