In 2011, STM Plastics acquired Heartland Plastics, a blow molding company specializing in small to medium sized production runs of polyethylene and polypropylene plastic bottles for health & beauty, food & drug, sports drinks, and more. STM continues to produce the high quality products that were associated with Heartland Plastics and has expanded the product line.

Bottles range in size from 8oz. to 32oz. and other custom items with part weights of under one pound, and while we maintain a stock FDA natural color, we have the ability to match any custom color.
