PE foam is a durable, lightweight, resilient, closed-cell material. It is often used for packaging industrial and agricultural goods due to its excellent vibration dampening and insulation properties. It also offers high resistance to chemicals and moisture.

A common classification of polyethylene, often used in manufacturing industries, is low-density polyurethane foam (PE foam). Polyethylene, abbreviated PE, is the most commonly used type of plastic, and is made up of ethylene monomers linked together.
