ESD Reclosable Pink Antistatic Bags 12x12 -- 4 mil

These 12" x 12" pink antistatic reclosable bags provide static dissipative protection for ESD-sensitive electronic components, PCBs, and assemblies. Certified to MIL-PRF-81705E Type II and EIA-541 standards, with surface resistivity below 1 x 10¹² ohms/sq for full static decay compliance. The single-track zipper closure with side seam welding supports repeated access without bag failure.

Specs: 12" x 12" | 4 mil | Pink Antistatic PE | 500/Case | MIL-PRF-81705E Type II | EIA-541

Applications

PCB and circuit board storage and transit, electronic component kitting, ESD-sensitive IC and chip packaging, small electronics assembly staging, semiconductor wafer and die protection, and electronics manufacturing work-in-progress inventory storage.

Features

• Surface resistivity < 1 x 10¹² ohms/sq for MIL-PRF-81705E Type II and EIA-541 static decay compliance


• Single-track zipper closure for repeated access without bag damage or seal failure


• Side seam welding to prevent bag splitting under repeated use


• Amine-free formulation — will not corrode or cloud polycarbonate components


• 4 mil construction for durability in production and storage environments


• 500 per case for production-volume ESD packaging operations

Material Notes

Pink antistatic bags are made from static dissipative polyethylene — the pink colorant indicates an antistatic formulation, which is the industry-standard color coding for this bag type. Unlike metallized shielding bags, pink antistatic bags dissipate surface static charge but do not provide a Faraday cage against external ESD events. For components requiring full electrostatic shielding, use a metallized barrier bag. Amine-free construction prevents the corrosion of polycarbonate and sensitive optical components that can occur with amine-based antistatic agents.

Use Case Notes

Pink antistatic bags are the standard packaging format for ESD-sensitive components in kitting, assembly, and storage operations that require repeated bag access. The reclosable zipper supports work-in-progress inventory where components are accessed multiple times before final assembly. The 12x12 square format accommodates most mid-size PCBs, sub-assemblies, and component trays. For long-term archival or shipping environments with high ESD risk, metallized shielding bags are preferred.

Common Questions

What is the difference between pink antistatic and silver shielding bags? Pink antistatic bags dissipate static that builds up on the bag surface, preventing charge transfer to enclosed components. Silver (metallized) shielding bags form a Faraday cage that also blocks external electrostatic fields. Pink antistatic bags are appropriate for controlled ESD environments; shielding bags are used when external field protection is also required.

Why amine-free? Some antistatic agents use amine compounds that migrate to the bag surface. Amine residues can corrode or cloud polycarbonate lenses, optical components, and sensitive plastics. Amine-free construction eliminates this risk for polycarbonate-containing electronic assemblies.

What standards do these meet? MIL-PRF-81705E Type II (military specification for ESD protective materials) and EIA-541 (Electronics Industries Alliance standard for packaging for ESD-sensitive items).
