Foam packaging, as commonly referred to, primarily refers to packaging products made from expandable polystyrene (EPS) material, which is formed through hot processing in molds and is colloquially known as "foam." Expandable polystyrene is an ideal packaging material that can be processed into various shapes and thicknesses according to requirements. 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 preservation. EPS packaging products are typically white but can be produced in colors upon request.
Key Features
1. Lightweight. EPS packaging products replace a portion of space with gas, containing 30 to 60 million independent 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 in the foam is dissipated through turbulent flow and compression, consuming and dissipating the incoming energy. The foam then terminates the shock load with a lower negative acceleration, thereby offering excellent shockproof performance.
