a19021400ux0100 Anti Static Shielding Bag 125x180mm 100 PCS

Anti-Static Shielding Bags 100 PCS

These anti-static shielding bags come in a pack of 100 pieces, each measuring 125mm by 180mm. They are designed for electronics professionals and hobbyists who need to store or transport sensitive components such as motherboards, RAM modules, processors and hard drives. The semi-transparent silver laminate lets you identify contents without opening the bag. They are not suited for buyers who need larger enclosures for full-size graphics cards or bulky assemblies.

Capacity and Effective Internal Space

Each bag offers a nominal 5 by 7 inch footprint, though the effective inner width may be 5 to 10mm less due to production tolerances. This size comfortably fits standard PCBs, memory sticks, CPUs and small daughter boards. It runs out when you try to insert ATX motherboards, full-length expansion cards or multiple stacked components that exceed the rectangular envelope.

Four-Layer APET/CPP Construction

The bags use a four-layer APET/CPP structure with double-sided 15 silk thickness to create a Faraday cage effect that isolates contents from electrostatic fields. The inner layer is static-dissipative polyethylene, while the outer silver laminate provides shielding and visibility. The flat open-top design allows quick insertion and heat sealing for secure closure during inter-company transfers or long-term storage.
