Foam packaging, as commonly referred to, primarily refers to packaging products made from expandable polystyrene (EPS) material, which is formed through thermal processing in molds and is colloquially known as "foam." Expandable polystyrene is an ideal packaging material, capable of being processed into various shapes and thicknesses of packaging products as needed. Under high load conditions, the material achieves shock absorption and vibration reduction through deformation, energy absorption, and energy decomposition. It also provides insulation and heat retention functions. EPS packaging products are typically white, but can be produced in colors upon request.
Primary Features
1. Lightweight. EPS packaging products replace part of the space with gas, containing 30 to 60 million separate 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 then terminates the shock load with a smaller negative acceleration, thereby providing excellent shock resistance.
