What are the characteristics of anti-static bags
Anti-static shielding bai bag It is compounded to produce product performance. It is widely used in the packaging of various pc boards, computer motherboards, sound cards, dao graphics cards, network cards and static-sensitive high-tech electronic products.
The characteristics of anti-static bag: anti-static packaging material is made of multiple layers of composite coating, the inner layer is a heat sealing layer, the strength of the sealed product is two times higher than the sealing strength of general materials; the middle layer is a high-strength mechanical layer, which has excellent Mechanical function; the outer layer is a conductive layer. The material is compatible with related chemical products and has good performance. During the packaging and storage process, it will not react with the packaged material and can be directly used for contact packaging of related products. Moisture resistance reaches level II, high and low temperature performance is ±500c. It has excellent comprehensive mechanical properties. It has been proved by mechanical strength and drop test of packaging transportation to meet the packaging strength requirements. It has good processability, the conductive layer adopts coating process, and can be processed into any shape according to user requirements. According to solvent migration test and aging performance test, the service life of the material is 18 years.
Anti-static bags are classified as: anti-static shielding bags, silver-gray transparent static bags, anti-static moisture-proof bags.
Anti-static bags can protect static-sensitive components to the greatest extent from potential electrostatic hazards. Their unique Faraday cage construction forms an "induction cover" effect to achieve shielding and anti-static effects on the contents of the bag. The outer layer is wear-resistant metal The coating and inner vinyl materials are treated with complex processes to achieve perfect electrostatic shielding protection. The translucent heat-sealed bag-shaped process can clearly identify the contents of the bag.
Anti-static bag advantages:
a. Prevent the occurrence of triboelectricity;
b. Free from the influence of electrostatic field;
c. Prevent direct discharge from contact with charged human bodies or charged objects.
It is difficult for a material to have all the above-mentioned properties at the same time. It is often necessary to use different materials to combine or compound to achieve the desired purpose. Where the static electricity is safely dissipated or the parts are shielded, the accumulation of electrostatic charge can be restricted or protected from Materials affected by external electrostatic charges can be used as ESD protective packaging materials.
Scope of anti-static bag: used for packaging of electronic products with anti-static requirements, such as various PC boards, IC integrated circuits, optical drives, hard drives, electronic components, etc.
