Companies that sell plastic drum barrels include The Cary Company, Basco and United States Plastics Corp. Plastic drum barrels are usually round in shape and come in a variety of colors and sizes. Plastic barrels have multipurpose uses, and many retailers sell models that are compliant with U.S. Food and Drug Administration standards.
The Cary Company sells plastic barrels with straight sides and tapered sides. Color choices of plastic drums at this retailer's site are limited to different shades of blue as of 2015. Drum capacity for straight-sided drums range from 30 gallons to 57 gallons, and capacity for its taper-sided drums range from 14 gallons to 55 gallons. In addition to size, plastic barrels are differentiated by barrel head type. The Cary Company offers plastic drums with open head or tight head tops.
Open head tops lift open, close easily and include a lever lock to secure contents. Tight head models have tops that are mostly sealed but have small openings for contents. Basco offers different models of closed head plastic barrels in colors such as black, red, yellow and natural, but drum size is limited to 55 gallons. The retailer sells plastic drums made of sturdy polyethylene plastic that doesn't rust or become dented.
