Foam packaging

Foam packaging, simply put, is the use of foam made of packaging. Commonly referred to as foam packaging, mainly refers to the expandable polystyrene (EPS) raw materials through the mold by the thermal processing, the production of packaging products commonly known as “foam.” Expandable polystyrene is an ideal packaging material, through the molding process, according to the need to be processed into a variety of shapes, different thickness of the packaging products. In the case of high load, the material through the deformation, energy absorption, decomposition of energy to achieve the buffer, damping effect, at the same time with insulation, thermal insulation function. EPS packaging products are generally white, according to the requirements of production color.

The main use of features:
1, light weight. Part of the space for EPS packaging products is replaced by gas, which contains between 300 and 6 million closed-cell blisters per cubic decimeter. So it is several times larger than the plastic volume to several times.
2, with the ability to absorb the impact load. EPS packing products by the impact load, the bubble of gas through the stagnation and compression, so that external energy consumption, dissipation, foam with a smaller negative acceleration, and gradually terminate the impact load, it has a better anti-shock effect.
3, good thermal insulation. Thermal conductivity is the weighted average of pure EPS thermal conductivity (108 cal / m.h. ° C) and air thermal conductivity (90 cal / m.h. ° C or so).
4, good sound insulation. EPS products mainly through sound insulation in two ways, one is to absorb the sound energy, reduce reflection and transmission; the second is to eliminate resonance and reduce noise.
5, anti-aging, corrosion performance. In addition to prolonged exposure to high-energy radiation, the product no obvious aging phenomenon. Can withstand many chemicals, such as dilute acid, dilute alkali, methanol, lime, asphalt and so on.
6, anti-static performance. Because EPS products have lower electrical conductivity, they are easy to produce self-charging phenomenon in friction, and will not affect general user’s products. For high-precision electronic products, especially modern large-scale integrated components of electrical components, should use anti-static EPS products.
