Embodiments of the invention blend polyethylene (PE), polypropylene (PP), and polystyrene (PS) with calcium carbonate (CC) or other filler(s) to form a single or multi-layer plastic film. The result is an improved plastic film that retains the beneficial properties of conventional plastic films, but can also be easily fractured and creased. Embodiments of the invention also provide a method for manufacturing the single or multi-layer plastic film.
