Anti-static and anti-piercing packaging bag

Abstract

The invention discloses an anti-static and anti-piercing packaging bag, belongs to the technical field of polymer materials, and aims at solving the problems of poor anti-static performance and stability, easily being scratched and pierced of an existing packaging bag. Aiming at solving the above problems, the invention discloses an anti-piercing packaging bag material with good stability and strong anti-static performance. The packaging bag comprises a bag body and an inner layer, the bag body is bonded with the inner layer through an adhesive, and the inner layer comprises, by weight, 30-60parts of natural rubber, 20-40 parts of thermoplastic elastomer, 10-20 parts of styrene-butadiene rubber, 5-15 parts of calcium carbonate, 5-8 parts of zinc oxide, 1-5 parts of white carbon black 1-6parts of emulsifier, 1-6 parts of non-polar solvent, 1-3 parts of quaternary ammonium salt, 1-3 parts of metal-salt, 0.1-1 part of dispersant and 0.5-2 parts of stabilizing agent. The inner layer material of the packaging bag has the advantages of being strong in anti-static performance and safe to human body, and the inner layer material is high-efficient and durable and has no environmental pollution.

Description

technical field [0001] The invention belongs to the field of polymer materials, and more specifically relates to an antistatic anti-puncture packaging bag. Background technique [0002] Anti-static packaging bags are packaging bags made of anti-static materials, also called anti-static shielding bags. It has the characteristics of "cannot afford" static electricity and can shield external static electricity. It is often used to package sensitive devices that are sensitive to static electricity and easily damaged by static electricity, such as the packaging of electronic circuit PCB boards or semi-finished products. [0003] At present, antistatic polymer materials are super sensitive to the surrounding environment, and are easily affected by the external environment and cause the loss of antistatic effect. In addition, because antistatic packaging bags are generally used for packaging electronic products, the electrical components of electronic products are easy to scratch o...
