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 depending on requirements 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 preservation. EPS packaging products are typically white, but can be produced in colors as requested.

Primary Usage Features

1. Lightweight. EPS packaging products replace part of the 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 within the foam dissipates and scatters the external energy through turbulence and compression, resulting in a smaller negative acceleration for the foam, which gradually terminates the shock load. Therefore, it offers excellent shock absorption properties.
