Wujiang anti-static shielding bags can effectively isolate objects with external electrostatic field, to prevent static bag to protect the items from static electricity hazards, but also anti-electromagnetic interference for the PCB, LED and other static-sensitive components. Wujiang anti-static shielding bags can be the greatest degree of protection of sensitive electronic components from electrostatic potential hazards. Their unique four-layer structure can be formed induction effect to protect the goods inside the static field. In addition there is a layer vinyl to eliminate static composition, it can prevent static electricity in the bag. This sealable bag is translucent, clearly recognizable from the outside can be internal items. The surface resistance can be achieved: 10Ω ~ 10Ω. Wujiang anti-static shielding bags composite Layer 2: (PE / VMPET or CPP / VMPET), with excellent anti-static, anti-RF, water vapor permeation, anti-salt spray, and many other functions, as well shielded from external personnel, equipment ESD electrostatic discharge and external electromagnetic radiation performance. Suitable for PCB, IC and other static-sensitive categories of high-tech electronic products transport and packaging. Packaging weight reduction will continue to make progress. From some of these projects can be clearly seen in the general trend to reduce packaging quality. Smaller weight plastic containers and flexible packaging, plastic bottles instead of glass and metal containers, can reduce the amplitude of ground transportation costs. Its development trend include: easy to pick up handling, required inventory that due to lighter packaging, pallet load is reduced accordingly, may reduce the spleen motorcycle and fork lifts; for the individual cartons, glass and plastic containers, and flexible packaging other food packaging container packing up, we need to increase their strength, in order to facilitate safe delivery of the store.
