material having performance of both the substrate and the film layers extruded films can be formed in accordance with the following representative direct extrusion film process blending and dosing storage comprising at least one hopper loader for thermoplastic polymer chip and optionally one for pelletized additive in thermoplastic carrier resin feed into variable speed augers the variable speed augers transfer predetermined amounts of polymer chip and additive pellet into a mixing hopper the mixing hopper contains a mixing propeller to further the homogeneity of the mixture basic volumetric systems such as that described are a minimum requirement for accurately blending the additive into the thermoplastic polymer the polymer chip and additive pellet blend feeds into a multi zone extruder upon mixing and extrusion from the multi zone extruder the polymer compound is conveyed via heated polymer piping through a screen changer wherein breaker plates having different screen meshes are employed to retain solid or semi molten polymer chips and other macroscopic debris the mixed polymer is then fed into a melt pump and then to a combining block the combining block allows for multiple film layers to be extruded the film layers being of either the same composition or fed from different systems as described above the.
