Anti-static bags for PCB board can protect electrically sensitive components from potential electrostatic hazards to a large extent. The unique four-layer structure of the PCB anti-static bag can form an induction effect to protect the contents of the bag from the electrostatic field. In addition, the inner layer is made of vinyl that can eliminate static electricity, which can prevent static electricity from being generated in the bag. Today, Nostal Packaging explains some knowledge about PCB anti-static bags:

This heat-sealable PCB board anti-static bag is translucent, and the contents inside can be clearly identified from the outside. The surface resistance value can reach: 10Ω～10Ω.

Introduction to the material and function of the anti-static bag for PCB board:

The PCB board anti-static bag adopts two-layer or four-layer composite: (VMPET/CPE or PET/AL/NY/CPE). The PCB board anti-static bag has excellent anti-static, anti-radio frequency, waterproof vapor penetration, and many other functions. There is also the ability to shield external personnel and equipment from ESD electrostatic discharge and external electromagnetic radiation. It is suitable for the transportation and packaging of high-tech electronic products such as PCB and IC that are sensitive to static electricity.

They have a unique four-layer structure that can form an “induction cover” effect to protect the contents of the bag from electrostatic fields. In addition, the inner layer is made of vinyl that can eliminate static electricity, which has excellent anti-static function. {PCB board anti-static bag} The inner and outer layers of the material are made of transparent anti-static material, with a semi-transparent conductive metal layer in the middle, so the PCB board anti-static bag has good anti-static and electrostatic shielding performance.

Principle of anti-static shielding bag

Principle: Faraday cage induction effect is formed in the bag.

Structure: Generally use two-layer or four-layer composite (VMPET/CPE or PET/AL/NY/CPE).

Scope of application: the outer packaging of static-sensitive circuit boards, precision parts, and electronic components.

Advantages: It has excellent anti-static, anti-radio frequency, waterproof vapor penetration, anti-salt spray and many other functions, as well as shielding external personnel and equipment from ESD electrostatic discharge and external electromagnetic radiation performance.

Purpose: to protect the contents of the bag from the electrostatic field to prevent the accumulation of static electricity, and avoid electrostatic hazards.

Types and characteristics of several anti-static bags commonly used in the electronics industry.

1) Shielding anti-static sealed bag

It is made of polyethylene and anti-static agent imported from Germany, blow-molded by special machinery. It is easy to pack and close with a finger. It can reduce complicated packaging procedures for you, and can be used for electronic originals and PCs. .. and other packaging. The surface resistance value is 109-10119.

2) PE red anti-static bag

The anti-static bag is the best packaging material for the printed circuit board, which can reliably release the static electricity generated by the printed circuit board and avoid damage. The technical indicators are as follows: in line with MIL-B-81705B; internal and external surface resistance 103r≤10119; electrostatic discharge time “2 seconds.

3) Anti-static shielding bag

In order to shield the plastic from electromagnetic waves, it is necessary to metalize the plastic with an antistatic agent, which has a good shielding effect. Surface resistance: 1069-1092.

4) Anti-static bubble bag

Anti-static bubble bag and bubble sheet can prevent the product from being damaged by collision or static electricity during production, handling and transportation. This bag is suitable for packaging electronic products that are sensitive to static electricity.

5) Anti-static and moisture-proof bag

It is suitable for the transportation and packaging of high-tech electronic products such as PCB and IC that are sensitive to static electricity. It has anti-static and moisture-proof functions. The inner and outer layers of the anti-static moisture-proof bag are made of transparent anti-static materials, and the middle layer is aluminum foil with excellent barrier properties and conductivity, so it has good anti-static, moisture-proof, electromagnetic shielding properties and silver-white appearance. It is mainly used in the packaging of electronic products that are sensitive to static electricity and need to be protected from moisture and electromagnetic interference.
