Manufacturer of foam boxHow to prevent static electricity in packaging

Foam packaging products have protective properties, buffering effect, and also have a certain anti-static effect in use. Why do foam packaging products have antistatic effect? Add anti-static agents. The method of adding anti-static agents is to improve the anti-static performance of the product in a short period of time. In the processing of foam packaging products, quaternary ammonium salt and phosphate antistatic agent can be directly added to the production, with better antistatic effect.

Add conductive fillers. Adding conductive materials is a method that can improve the antistatic performance of foam packaging products for a long time. The application principle is to form a stable conductive path inside the raw materials of the entire foam packaging product by adding conductive materials, so as to play a good anti-static role in future use. Usually, the conductive material used is carbon black.

These two methods can improve the anti-static effect of foam packaging products to a certain extent, but sometimes it is difficult to meet the user's anti-static performance requirements. At this point, users can combine two anti-static methods simultaneously. Adopting. Under normal circumstances, adding conductive materials and antistatic agents in the processing of foam packaging products can have a good antistatic effect.

What are the advantages of using foam packaging?

1. Good insulation performance, thermal conductivity is the weighted average of pure EPS thermal conductivity and air thermal conductivity.

2. The sound insulation performance of EPS products is good. There are two main ways to achieve sound insulation: one is to absorb sound energy and reduce reflection and transmission; The second is to eliminate resonance and reduce noise.

3. Lightweight. Part of the space for EPS packaging products is replaced by gas. Each cubic centimeter contains 3 to 6 million independent closed vapor bubbles, making it several to several tens of times larger than plastic.

4. Anti aging and corrosion performance. Except long-term exposure to high-energy radiation, the product has no obvious aging phenomenon and can withstand a variety of chemicals, such as dilute acid, dilute alkali, methanol, lime, asphalt, etc

5. Able to absorb impact loads. When EPS packaging products bear impact load, the gas in foam will stagnate and compress, thus consuming and dissipating external energy. The foam body gradually terminates the impact load with a small negative acceleration. Therefore, it has good shockproof effect.

6. Antistatic performance. Due to the low conductivity of EPS products, they are prone to self charging during friction and will not affect the products of ordinary users. For high-precision electronic products, especially large integrated block structures of modern electrical appliances, please use anti-static EPS products for components.
