Foam packaging, as commonly referred to, primarily consists of expandable polystyrene (EPS) material that is molded and heat-processed to create packaging products, which are colloquially known as "foam." Expandable polystyrene is an ideal packaging material, capable of being formed into various shapes and thicknesses as required. 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. Possesses the ability to absorb shock loads. When EPS packaging products are subjected to shock loads, the gas within the foam dissipates and scatters the incoming energy through turbulence and compression, thereby gradually terminating the shock loads with a smaller negative acceleration, offering superior shock resistance.
