core tip: foam packaging, in short, is a packaging made of foam. Generally speaking, foam packaging mainly refers to the packaging products made of expandable polystyrene (EPS) raw materials through thermal processing through molds, commonly known as "foam". Expandable polystyrene is an ideal packaging material. Through the molding process, it can be processed into packaging products of various shapes and thicknesses according to needs. In the case of high load, the material has the functions of cushioning and shock absorption through deformation, energy absorption and energy decomposition, as well as heat preservation and insulation. EPS packaging products are generally white, and color can be produced according to requirements. Main application characteristics: light weight, with the ability to absorb impact load, good heat insulation performance, sound insulation performance, anti-aging, corrosion performance, anti-static performance

[China Packaging News] foam packaging, in short, is the packaging made of foam. Generally speaking, foam packaging mainly refers to the packaging products made of expandable polystyrene (EPS) raw materials through thermal processing through molds, commonly known as "foam". Expandable polystyrene is an ideal packaging material. Through the molding process, it can be processed into packaging products of various shapes and thicknesses according to needs, which saves 70% energy than the existing market experimental machines. In the case of high load, the material has the functions of cushioning and shock absorption through deformation, energy absorption and energy decomposition, as well as heat preservation and insulation. EPS packaging products are generally white, and color can be produced according to requirements. Main application characteristics: light weight, with the ability to absorb impact load, good heat insulation performance, sound insulation performance, anti-aging, corrosion performance and anti-static performance in this smile

1, light weight. Part of the space of EPS packaging products is replaced by gas, and there are 10000 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 load, the gas in foam will consume and dissipate 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 shock proof effect

3. Good heat insulation performance. Thermal conductivity is the weighted average of pure EPS thermal conductivity (108cal/M.H. ℃) and air thermal conductivity (about 90cal/M.H. ℃) for 15 years since the development of this process

4. Good sound insulation performance. The sound insulation of EPS products is mainly through two ways: one is to absorb sound energy and reduce reflection and transmission; Second, 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. It can withstand many chemical substances, such as dilute acid, dilute alkali, methanol, lime, asphalt, etc

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