New arrival, green antistatic PE bag
Antistatic PE bag is made of polyethylene (PE) as the base material, and is made by adding (semi) permanent antistatic masterbatch, color masterbatch and stabilizer to blend and blow film. It has the flexibility and transparency of ordinary PE bags, and also has the function of conducting static electricity. Its core technology is that the antistatic agent forms an alloy structure with the resin to form a linear or mesh "conductive channel" to ensure that the charge can be released quickly.
1. Technical characteristics
Resistance range
The surface resistance is usually controlled at 10⁶Ω to 10⁹Ω (inner layer) or less than 10⁸Ω (outer layer), and the static decay time is less than 2 seconds, which meets the MIL-B-81705B standard.
Stability
The antistatic performance is not affected by temperature and humidity. Products using permanent antistatic agents can still maintain a stable effect in a dry environment, avoiding the problem of ordinary antistatic bags failing due to reduced humidity or prolonged storage time.
Physical properties
The thickness can be customized (0.03mm-0.2mm), with both buffering and flexibility, suitable for packaging electronic products of different sizes.
2. Application fields
Electronic industry
Widely used for inner/outer packaging of electrostatic sensitive components such as printed circuit boards (PCBs), chips, hard disks, LEDs, etc., to avoid component breakdown caused by friction static electricity.
Special scenarios
Black conductive PE bags are suitable for light-sensitive components due to their strong light-shielding properties; mesh bags enhance electrostatic dissipation capabilities through conductive pattern design and are mostly used for PCB board packaging.
3. Selection points
Material verification: Products with permanent antistatic technology are preferred to avoid the failure of short-term antistatic agents due to migration.
Environmental adaptation: High temperature environments (>60°C) require heat-resistant materials (such as polyimide), and low temperature scenes should pay attention to preventing brittle cracking.
Specification matching: Small components use a thickness of 0.03-0.06mm, and large equipment recommends a 0.1-0.2mm thickened version to enhance protection.
Antistatic PE bags balance cost and protection performance in electronic product packaging through material optimization and structural design, becoming an indispensable consumable in the electronics manufacturing industry.
