Foam packaging, as commonly referred to, primarily consists of expandable polystyrene (EPS) material that is formed into various shapes and thicknesses through molding and heat processing. The resulting packaging products are colloquially known as "foam." Expandable polystyrene is an ideal packaging material, capable of being processed into different shapes and thicknesses as needed. Under high loads, the material achieves shock absorption and vibration reduction through deformation, energy absorption, and energy dissipation. It also offers thermal insulation and heat preservation properties. EPS packaging products are typically white, but can be produced in color upon request.

Primary Features

1. Lightweight. EPS packaging products replace part of the space with gas, containing 30 to 60 million independent sealed air bubbles per cubic decimeter. Therefore, it is several to tens of times larger in volume than plastic.

2. Capable of absorbing shock loads. When EPS packaging products are subjected to shock loads, the gas within the foam undergoes turbulent flow and compression, dissipating the incoming energy. The foam terminates the shock load with a lower negative acceleration, thus providing excellent shockproofing effects.
