Moisture Barrier Bag Dri-Shield® 3400
Meets ANSI/ESD S20.20, Packaging standard ANSI/ESD S541,
Static Control Bag ANSI/ESD S11.4 Level 1, and IPC/JEDEC J-STD-033.
This foil moisture barrier bag is designed to provide protection for ESD
sensitive and moisture sensitive electronics, typically SMT (Surface
Mount Technology) items. Best practice is to use with Desiccant and a
Humidity Indicator Card. The bags are heat sealable and suitable for
vacuum packaging. Bags are printed with ESD protective and moisture
sensitive warning symbols, and a lot code for traceability.

This product is intended for commercial use only. This product is not on the Qualified Product
Listing under the Defense Standardization Program.
NOTE: The complete dry package concept of packaging for electronics requires three elements:
Moisture Barrier Bags - To Protect
Desiccants - To Absorb Moisture
SCS Moisture Barrier Bags are packaged in a polyethylene bag.
Humidity Indicator Cards - To Monitor Performance
