Foam box is commonly called "foam box". It is mainly made up of EPS material, which is heated by mould. The product is usually called "foam box". Expandable polystyrene is an ideal packaging material. It can be processed into packaging products of various shapes and thicknesses according to needs through molding process. Under high load conditions, the material achieves the effect of cushioning and shock absorption through deformation, energy absorption and energy decomposition, and has the functions of thermal insulation and heat insulation. Foam boxes are generally white, and colors can be produced according to requirements. 1. Light weight. Some spaces of EPS packaging products are replaced by gas, containing 3-6 million independent sealed bubbles per cubic decimeter. So it is several times to dozens of times larger than plastic.
2. It has the ability to absorb impact load. When the EPS packaging product is subjected to impact loading, the gas in the foam consumes and releases external energy through stagnation and compression. The foam gradually terminates the impact load with smaller negative acceleration, so it has good shockproof effect. 3. Good thermal 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. There are two main ways for sound insulation of EPS products: one is to absorb sound wave energy and reduce reflection and transmission; Second, eliminate resonance and reduce noise. 5. anti-aging and corrosion resistance. Except long-term exposure to high-energy radiation, the product has no obvious aging phenomenon. It can withstand many chemicals, such as dilute acid, dilute alkali, methanol, lime, asphalt, etc.
Sixth, antistatic performance. Because the conductivity of EPS products is low, it is easy to produce its own electrification phenomenon in the friction process, which has no impact on the products of general users. For high-precision electronic products, especially modern electrical large integrated block structural elements, antistatic foam box equipment should be used. The uses and advantages of foam plastic box production equipment are very popular nowadays. These packaging products can be seen in many fields. As a common package, the price of foam plastic packaging is also very cheap, compared with other transport tools, it is more suitable for packaging.
