An innovative flat extrusion die system multiplies key functional layers in cast film, creating “microlayers” that substantially improve a substrate’s properties, including impact strength, elongation, oxygen and moisture barrier, without increasing overall thickness or raw material content. Called a “layer multiplier,” the flat die system transforms a typical sandwich structure from a standard coextrusion feedblock into a structure in which one or more of the layers has been subdivided into multiple microlayers.
