LK® BB361218 – 12×18″ Anti-Static Moisture Barrier Bag | 3.6 Mil | 200/CS

LK® BB361218 – 12×18″ Anti-Static Moisture Barrier Bag | 3.6 Mil | 200/CS

The LK® BB361218 is a 12×18″ anti-static moisture barrier bag engineered from 3.6 mil multi-layer barrier film. Designed for dry packaging of moisture-sensitive electronic components (MSDs), these bags provide waterproof, vapor-proof, and greaseproof protection combined with ESD and EMI/RFI shielding that meets EIA Std. 541 and EIA Std. 583 Class 1 requirements. Each case contains 200 heat-sealable bags ready for production-line use.

What electronic components and industries use 12×18″ moisture barrier bags?

The 12×18″ barrier bag accommodates a broad range of moisture-sensitive devices, including mid-size PCB assemblies, IC chip trays, populated board modules, SSD drives, and MEMS sensor packages. Contract electronics manufacturers, defense electronics integrators, automotive electronics OEMs, and semiconductor distributors rely on this format for J-STD-033D-compliant MSD dry-pack shipments at sensitivity levels 2 through 5.

3.6 Mil Laminated Barrier Film: ESD, EMI/RFI, and Vapor Control

The BB361218’s 3.6 mil laminated structure combines a metalized shielding layer with a static-dissipative outer surface and a heat-sealable polyethylene interior. This construction delivers surface resistivity in the EIA Std. 541 range, a moisture vapor transmission rate (MVTR) well below long-term MSD storage thresholds, and reliable impulse-seal integrity. The inner layer bonds cleanly on standard constant-heat and impulse sealers at typical PE settings.

J-STD-033D Dry-Pack Compliance for MSD Level 2–5 Shipments

Shipping MSDs at sensitivity levels 2 through 5 requires barrier packaging capable of holding internal humidity below 10% RH throughout transit and storage. The LK® BB361218, used with desiccant packets and humidity indicator cards, satisfies the dry-pack material requirements of IPC/JEDEC J-STD-033D — making it the correct packaging selection for component manufacturers shipping to SMT assembly lines and for distributors maintaining shelf-life integrity on packaged IC lots.
