About Foam

Super-Cushioning Polyethylene Foam Sheets and Strips

Also known as Ethafoam, these polyethylene foam sheets and strips are widely used in packaging applications to absorb shock and damp vibration. Polyethylene foam offers better resistance to chemicals than polyurethane foam and is also superior when insulating packaged objects from external temperatures. Foam has closed-cell construction, which restricts water, air, and gases from being absorbed.

Foam with ultra-smooth texture has a sleek surface that's easy to wipe down.

Extra-Tough Super-Cushioning Polyethylene Foam Sheets and Strips

These sheets and strips are made of cross-linked polyethylene, so they are stronger and more chemical resistant than other types of polyethylene foam. They also have excellent buoyancy and resist mildew. These sheets and strips are widely used in packaging applications to absorb shock and damp vibration. Foam has closed-cell construction, which restricts water, air, and gases from being absorbed.
