ABSTRACT:
A polymeric multilayer film structure having a high percentage of fillers is disclosed. The fillers are concentrated in a separate filler containing layer having about 5 to about 20 percent of the thickness of the total multilayer film. The filler containing layer is coextruded with a base layer comprising the balance of the thickness of the multilayer film. By keeping the filler containing layer thin, relative to the total film thickness, a multilayer film having a filler concentration up to about 60 weight percent is achievable without significantly adversely affecting the material properties of the multilayer film structure.
