Foam packaging, as commonly referred to, primarily consists of expandable polystyrene (EPS) material that is molded and heat-processed to create packaging products, commonly known as "foam." Expandable polystyrene is an ideal packaging material, which can be processed into various shapes and thicknesses as needed through molding techniques. Under high loads, the material achieves shock absorption and vibration reduction through deformation, energy absorption, and energy dissipation. It also provides thermal insulation and heat preservation. EPS packaging products are typically white, but can be produced in colors as required.
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 dissipates and scatters the incoming energy through turbulent flow and compression, allowing the shock load to be gradually terminated with a lower negative acceleration, thus offering excellent shock resistance.
