What is foam plastic packaging?

foam plastic packaging, global plasticization that foam plastic packaging is made of foam. Generally speaking, foam packaging is mainly made up of EPS materials, which are processed by hot working through moulds. The packaged products are commonly called “foam”. It is an ideal packaging material that can be processed into different shapes according to different packaging thickness. In the case of high load, the material can achieve the functions of cushioning and shock absorption through deformation, energy absorption and energy decomposition. At the same time, it has the functions of heat preservation and heat insulation. EPS packaging products are generally white, and color can be produced according to requirements
main features:

1. Light weight. Part of the space of EPS packaging products is replaced by gas, and there are 3-6 million independent closed bubbles per cubic decimeter. Therefore, it is several times to dozens of times larger than plastic

2. It has the ability to absorb impact load. When EPS packaging products are subjected to impact loading, the gas in the foam will be dissipated and dissipated by stagnation and compression, and the bubble will gradually terminate the impact load with smaller negative acceleration. Therefore, it will have a better seismic effect. Br>
3. Good heat insulation performance. The thermal conductivity is the weighted average of pure EPS thermal conductivity (108cal /M.H. ℃) and air thermal conductivity (about 90cal /M.H. ℃)

4. Good sound insulation performance. The sound insulation of EPS products is mainly through two ways: one is to absorb acoustic energy and reduce reflection and transmission; Second, eliminate resonance and reduce noise

5, anti-aging and corrosion resistance. Except for long-term exposure to high-energy radiation, the product has no obvious aging phenomenon. It can tolerate many chemicals, such as dilute acid, dilute alkali, methanol, lime, asphalt, etc

6. Anti static performance. Because EPS products have low conductivity, it is easy to produce self electrification in friction, which will not affect the products of ordinary users. For high-precision electronic products, especially large-scale integrated block structural components of modern electrical appliances, anti-static EPS products should be used
