StratoGrey™ Static Shielding Zipper Bags are designed to safeguard static-sensitive devices from electrostatic discharge during packaging, storage, and transport. Unlike standard anti-static bags, these static shielding zipper bags incorporate a buried metal layer within the film structure, creating a protective barrier that helps shield contents from external static fields.
The multi-layer construction typically consists of a dissipative outer layer, a buried metal shield, and a static-dissipative interior. This configuration creates a Faraday cage effect around the contents when properly sealed. The buried metal design provides enhanced durability compared to surface metalized films, reducing the risk of abrasion-related failures during handling.
The interior of StratoGrey™ bags is amine- and amide-free, helping prevent corrosion or chemical interaction with sensitive polycarbonate boards and electronic assemblies. The low-outgassing material supports clean packaging environments where component integrity is critical. The semi-transparent grey film allows for quick visual identification of packaged items without opening the bag, improving workflow efficiency in kitting and inspection operations.
Each bag features a reclosable zipper closure, making it suitable for applications where components must be accessed multiple times. This design is particularly beneficial for repair stations, quality control departments, field service kits, and staged production runs. The 3/8" side seal enhances mechanical strength and helps maintain packaging integrity during shipping and warehouse handling.
StratoGrey™ Static Shielding Zipper Bags are commonly used across:
- PCB manufacturing and assembly
- Semiconductor and microelectronics distribution
- Aerospace and defense electronics
- Automotive control modules
- Telecommunications equipment
- Medical electronic devices
Available in multiple sizes and standard thickness configurations, these static shielding zipper bags support a wide range of component dimensions, from small integrated circuits to larger circuit boards. Selecting the appropriate size and mil thickness ensures optimal protection and handling performance.
For commercial buyers, bulk case quantities allow for streamlined procurement and inventory management within ESD-controlled facilities. These bags are suited for use in EPA (Electrostatic Protected Areas) and throughout supply chains where shielding-level protection is required.
When compared to pink anti-static bags, StratoGrey™ Static Shielding Zipper Bags provide a higher level of ESD protection due to their buried metal construction. They are appropriate when both static charge generation control and shielding from external electrostatic fields are necessary.
Universal Plastic supplies StratoGrey™ Static Shielding Zipper Bags to support manufacturers, contract assemblers, and distributors seeking dependable ESD packaging solutions for sensitive electronics.
FAQs
What is the difference between anti-static and static shielding zipper bags?
Anti-static bags reduce static generation, while static shielding zipper bags include a metal layer that shields contents from external electrostatic fields.
What does buried metal construction mean?
Buried metal construction refers to a metal layer embedded within the film structure, protecting it from abrasion and enhancing shielding performance.
Are StratoGrey™ bags safe for polycarbonate circuit boards?
Yes. The interior is amine- and amide-free, reducing the risk of corrosion or chemical damage to sensitive materials.
Why choose a zipper closure for static shielding bags?
The reclosable zipper allows repeated access to components without compromising shielding protection when properly sealed.
Can these bags be purchased in bulk quantities?
Yes. StratoGrey™ Static Shielding Zipper Bags are available in wholesale case quantities for commercial and industrial buyers.
