Polystarch Masterbatch products have been developed for use in blown film, injection molding and other application of Polyethylene and Polypropylene resins. The Masterbatch contains a patented mix of compatabilizers and additives that alloy the starch to the plastic matrix. These formulations and their potential for use with a broad range of additives give Polystarch Masterbatch major advantages in injection molding, blown film, and many other processes.
