Memory Module & Sensitive IC Antistatic Bags 8x12 — 4 mil Pink
4 mil pink antistatic bags for ESD-sensitive electronic component packaging where charge generation prevention is required. Amine-free formulation prevents polycarbonate corrosion and delivers consistent anti-static performance in low-humidity environments where standard antistatic additives degrade. Surface resistivity less than 1 × 10¹² ohms/sq meets full static decay requirements of MIL-PRF-81705E, Type II and EIA-541.
Specs: 8" x 12" | 4 mil | Pink Antistatic Poly | Amine-Free | MIL-PRF-81705E Type II / EIA-541

Material Notes
Pink antistatic bags use surface-active additives (anti-static agents) incorporated into the poly film to dissipate static charges generated by contact and separation. Unlike static shielding bags, antistatic bags do not provide Faraday cage protection against external ESD events — they prevent charge buildup on and in the bag itself. The amine-free formulation removes the risk of amine migration causing contact corrosion on sensitive polycarbonate and metal contacts.
Use Case Notes
The 8x12 format is well-suited for DDR memory modules, standard 2.5-inch drive sizes, mid-size PCBs, and IC tray sets. Recommended for components that require protection from triboelectric charging during transit but do not require full Faraday cage shielding from external ESD sources.
Common Questions
Q: What is the difference between antistatic (pink) and static shielding (metallic) bags?
A: Pink antistatic bags prevent static charge generation on the bag surface but do not block external ESD events. Static shielding bags provide complete Faraday cage protection. Use antistatic bags for ESD-controlled environments; use static shielding bags when external ESD exposure is a risk during transit or handling.
Q: Why does amine-free matter?
A: Conventional anti-static additives often contain amines, which can migrate and corrode polycarbonate plastic connectors, housings, and contacts. Amine-free formulation eliminates this risk for assemblies with polycarbonate components.
Q: Can these bags be heat sealed?
A: Yes. Compatible with standard impulse and heat bar sealers for closed-end packaging.
Why Buy
A specification-grade antistatic bag for electronics manufacturing and distribution operations with compliance requirements. The amine-free, polycarbonate-safe formulation addresses a common failure mode in standard pink poly bags, and the MIL-PRF-81705E Type II certification supports defense and aerospace supplier qualification requirements.
