Abstract: A method of manufacturing a film includes forming a blend containing a renewable content starch, a renewable content mineral, and polyethylene, operating a mass flow hopper to maintain a consistent mass flow rate of the blend to a feed throat of an extruder, and operating the extruder with a screw speed and melt temperature based on the amount by weight of the starch and mineral within the blend. The melt is passed through a screen pack with a mesh rating based on the amount by weight of the starch and mineral within the blend, is passed through a die, and is cooled into a film. The film is nipped to a gauge such that the film can be formed into a bag.
