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 decomposition, while also providing thermal insulation and heat retention. 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 dozens 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 lower negative acceleration, gradually, thus providing excellent shock absorption properties.
