At Discovery Plastics, we specialize in polyethylene and polypropylene resins, ranging from low-melt to high-melt flow. Shot sizes range from 4.4 ounces, to 235 ounces. You can bet that if you have a product, we have the equipment to produce it.

Our expertise in molding polyolefin resins is unrivaled by our competition. Depending on your needs, these resins are usually bought by the rail car. We generally have roughly 880,000 pounds on hand in our silos. We also have a 107,000 sq. ft. warehouse off-site to accommodate truckload shipping.
