Due to increased market demand,Foam packaging manufacturerMore and more.

Foam packaging, in short, is the packaging made of foam. Generally speaking, the foam packaging is mainly made of expandable polystyrene (EPS) raw materials by hot processing through molds. The packaging products produced are commonly known as "foam".

Disposable polystyrene is an ideal packaging material. Through the molding process, packaging products of various shapes and thicknesses can be processed according to requirements. Under high loads, materials achieve cushioning and shock absorption through deformation, energy absorption, decomposition energy, etc., and have the function of thermal insulation.

EPS packaging products are generally white and can be produced in color according to requirements.

Main usage characteristics:

1. Lightweight. Part of the space for EPS packaging products is replaced by gas, with 3 to 6 million independent sealed bubbles per cubic centimeter of volume. Therefore, it is several to tens of times larger in volume than plastic.

2. Have the ability to absorb impact loads. When EPS packaging products are subjected to impact load, the gas in the foam will consume and dissipate the external energy through stagnation and compression, and the foam body will gradually terminate the impact load with a small negative acceleration, so it has a good shockproof effect.

3. Good insulation performance. The thermal conductivity is the weighted average of the pure EPS thermal conductivity (108cal/m.h. ℃) and the air thermal conductivity (around 90cal/m.h. ℃).

4. The sound insulation effect is very good. The product is mainly soundproofed in two ways. One is to absorb sound energy, reduce reflection and transmission; The second is to eliminate resonance and reduce noise.

5. Anti aging and corrosion performance. Except for long-term exposure to high-energy radiation, the product has no obvious aging phenomenon. Can tolerate many chemical substances, such as dilute acids, dilute alkalis, methanol, lime, asphalt, etc.

6. Anti static performance. Due to the low conductivity of EPS products, they are prone to self charging during friction, which is detrimental to ordinaryThe user product will not cause any impact. For high-precision electronic products, especially modern electrical large-scale integrated block structural components, anti-static EPS products should be used.
