摘要 |
A polymeric multilayer film having a high percentage of fillers to increase the opacity of the film is disclosed. The fillers are concentrated in a separate filler containing layer having about 20 to about 60 weight percent fillers uniformly dispersed therein and about 30 to about 70 percent of the thickness of the total multilayer film. The filler containing layer is coextruded with the outer layers comprising the balance of the thickness of the multilayer film. The multilayer film has at least 15 weight percent fillers. |
