Today, we will introduce several types frequently used in the electronics industry Anti-static plastic bags and their advantages. Let's take a look!
1) Shielding anti-static resealable bags
These are made of polyethylene and German-imported anti-static agents through special injection molding. They are easy to package and close with a pinch. This reduces complicated packaging procedures and is suitable for packaging electrical components, PCs, etc. Surface resistivity is 10^6-10^11Ω.
2) PE bright red anti-static plastic bag
This Anti-static plastic bags is an excellent packaging material for printed circuit boards, allowing for reliable release of static electricity generated by printed circuit boards and preventing damage.
3) Anti-static shielding bag
In order to enable plastics to shield electromagnetic waves, anti-static agents need to be applied to the plastics for coating treatment, which has a good shielding effect.
4) Anti-static bubble film
Anti-static bubble film and bubble wrap can prevent damage to products caused by impact or static electricity during manufacturing, transportation, and shipping. This bag is suitable for packaging static-sensitive electronic products.
5) Anti-static and moisture-proof bag
Suitable for the transportation and packaging of static-sensitive high-tech electronic products such as PCBs and ICs. It has anti-static and waterproof functions. The inner layer of the anti-static and moisture-proof bag is made of transparent anti-static material, and the inner layer is aluminum foil, with excellent high barrier and conductivity. Therefore, it has good anti-static, waterproof, and electromagnetic shielding properties, and its appearance is silver. It is mainly used for packaging electronic products that are sensitive to static electricity, and also require waterproof and anti-electromagnetic interference.
According to the processing technology, it can be divided into two categories:
First, it is made of sheet material, metal coating layer, and heat-permeable layer double-layer processing. It has the dual functions of "eliminating" static electricity itself and shielding external static electricity.
Second, PE anti-static plastic bags, mainly in the film blowing machine stage of production, add anti-static particles to the raw material particles to achieve the purpose of having an anti-static effect. It has the characteristics of simple manufacturing process and low production cost.
Based on these classifications, several common types are introduced below Anti-static plastic bags types.
Anti-static PE bag
Anti-static PE bags are made by blow molding a mixture of high-pressure polyethylene (LDPE) + linear high-pressure polyethylene (LLDPE) + anti-static masterbatch + color masterbatch + thickener, and then sealing and cutting. This product has all the characteristics of ordinary PE bags and anti-static function. Its raw material feels relatively soft, and the thickness can be adjusted freely. It is widely used in general electronic devices such as integrated circuits. As an outer packaging, it reduces costs and protects electronic devices from static electricity damage to electronic components due to friction between insulators.
The characteristics of this type of packaging bag are low price, and the main disadvantage is that the anti-static value cannot be too high, especially in the dry season in the north, suitable for products with insufficient anti-static requirements.
