*** Moisture Barrier Bag Dri-Shield® 2000 *** This aluminized moisture barrier bag is designed to provide packaging for ESD and moisture sensitive items, both inside and outside an ESD protected area. The bags are heat sealable and suitable for vacuum packaging. Bags are printed with ESD and moisture warning symbols and a lot code for traceability. They are manufactured from a laminate of multiple layers of aluminized polyester and polyethylene. Polyester provides puncture resistance. Metal layers are intended to provide shielding of Electrostatic Discharge (ESD) and to help minimize the penetration of electric field while providing moisture protection.
