What are the types of anti-static plastic bags? What is the production process?

Most of the anti-static plastic bags are made of anti-static materials, generally two-layer composite or four-layer structure. The purpose of this is to better protect the wrapped items from the hazards of static electricity. By wrapping the air in the film to achieve a good buffering effect, the production purpose of anti-static plastic bags is generally for electrostatic protection. Suitable for packaging of various industries or products, such as some medical supplies, raw chemical or mechanical equipment, component protection of electronic computers, etc. Especially for electronic products or mechanical products, anti-static bags are more needed because they contain electromechanical components. 

In fact, in addition to anti-static plastic bags, there are many types of anti-static packaging products, such as anti-static shielding bags, sponges, mesh, bubble bags and so on. The principle of the bubble bag is that the film contains air to form bubbles to prevent the product from impacting, to ensure that the product is protected when it is shaken, and it also has the effect of thermal insulation, suitable for different product packaging or turnover in all walks of life. . These protective materials can be classified according to the production process before and after, and the crafts are also different, with their own strengths and advantages.

The selection principle of anti-static packaging, in order to ensure the maintenance of electrostatic protection, the selection of packaging materials should be based on the product's electrostatic protection principle, product characteristics and different methods of use.

1. Prevention of charge dissipation and triboelectric electrification. Packaging materials that come into contact with ESDS products, including fillers, should be static-dissipative or materials that do not easily generate static electricity.

2. Measures for electrostatic shielding. When handling and storing products outside of ESD-protected work areas, ESDS products should be packaged in electrostatically conductive and electrostatically shielded packaging containers. The outer packaging box should generally be a metal box with good shielding and conductive surface, and the shell can be solid core type or non-solid core type (such as metal mesh).

3. Ground the package. All indirect packaging materials that wrap or encapsulate ESDS products shall be capable of dissipating electrostatic charge (grounded) within the ESD-protected work area.

4. Maintain the anti-static properties of the material. During the delivery, packaging, storage and transportation stages of ESDS products, the packaging materials used or reused should always check the anti-static properties such as static dissipation, shielding properties and triboelectricity to keep them basically unchanged.
