01 What is an anti-static shielding bag?

Anti-static shielding bag is generally called: anti-static bag, shielding bag, waterproof bag, with excellent waterproof fireproof, gas barrier waterproof, antistatic effect, because the vast majority of electronic equipment in the transportation will be damaged by electrostatic induction, so customers will choose anti-static shielding bag as a packaging to protect electronic equipment.

02 How did the anti-static shielding bag come about?

Common equipment and electronic components produce static electricity phenomenon mainly from two situations: one is friction electricity, when two objects friction, the charge on the surface of the object will be transferred and redistributed, when the charge is concentrated on an object or surface to form static electricity; The second is contact with charge, contact with charged body, will receive charge, so as to carry the same polarity of static electricity, especially when there is a large amount of ionized charge in the air, it is easy to generate static electricity. As a result, the electronic components are damaged and the normal use is affected.

In order to avoid static electricity and reduce the damage to such sensitive devices, people began to use anti-static bags to package, which is generally made of LDPE and LLDPE particles blown film bags, and then add anti-static agents to produce anti-static effects, the function is to prevent static electricity, that is, to inhibit the friction between built-in items and packaging bags when moving to generate static electricity. However, when the external electrostatic discharge occurs, because the ordinary anti-static bag only has the characteristics of preventing the generation of internal static electricity, it cannot avoid the damage of the external electrostatic discharge to the product, resulting in damage to the sensitive devices in the bag, thereby affecting the use and even affecting the reputation of the enterprise.

In order to avoid the occurrence of the above events, anti-static shielding bags have been developed and have received a good response, and the application field of anti-static shielding bags is constantly expanding. Anti-static shielding bag This kind of bag is very special, when packaging sensitive devices, it can not only prevent static electricity inside the package, but also shield external personnel and equipment electrostatic discharge and electromagnetic radiation, double protection of the sensitive devices inside the package from damage.

03 What is the function of anti-static shielding bag?

Generally, the anti-static shielding bag adopts a two-layer composite or higher four-layer structure, and the Faraday cage induction cover effect is formed in the bag, which protects the contents of the bag from the electrostatic field to the greatest extent, prevents the accumulation of static electricity, and protects it from potential electrostatic hazards; Anti-static shielding bag can shield ESD electrostatic discharge and electromagnetic radiation of external equipment, and also has certain anti-radio frequency, waterproof steam penetration, anti-salt spray (customized according to customer needs) and other properties.

For example, some sensitive devices are of qualified quality and standardized use of anti-static packaging bags for packaging, but after receiving the product and opening the package, the customer found that some devices were damaged and could not work normally, the reason is that the ordinary anti-static bag can not shield the external electrostatic discharge, may be damaged by the external electrostatic discharge during the product transportation, resulting in damage to the product device. If an anti-static shielding bag is used to package in this case, it can not only prevent static electricity in the bag, but also shield the external electrostatic discharge, and the product device will not be damaged.

Therefore, according to the product demand, it is very important to choose the right anti-static packaging bag!
