Drum (container)
A drum (also called a barrel) is a cylindrical shipping container used for shipping bulk cargo. Drums can be made of steel, dense paperboard (commonly called a fiber drum), or plastic, and are generally used for the transportation and storage of liquids and powders. Drums are often stackable, and have dimensions designed for efficient warehouse and logistics use. This type of packaging is frequently certified for transporting dangerous goods. Proper shipment requires the drum to comply with all applicable regulations.[1]
Plastic drums are typically made of blow molded high density polyethylene.[20][21] They are available in a variety of sizes and constructions designed for specific purposes and markets. Plastic drums are used for liquids, granular solids, and inner packages. When designed, tested, and labeled, plastic drums can be used with dangerous goods or hazardous materials.
The plastic drum, inner coating, or drum liner should be compatible with the intended contents. Foods and pharmaceuticals can be particularly sensitive. Some liquid chemicals can permeate through plastics or can cause embrittlement.[22]
The compression stability of plastic drums can be sensitive to heat. The Plastic Drum Institute does not recommend stacking when temperatures are above about 32 °C (90 °F).[23] Some methods of reinforcing the sidewalls are available. [24]

Plastic drums are used for more than shipping containers. They can be used for water collection and storage. Also, plastic drums are used along highways to mark construction zones.[26]
