3M Moisture Barrier Bags Dri-Shield 2700 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.
With almost twice the puncture resistance of the Dri-Shield 2000, 3.6 mil, the Dri-Shield 2700 Moisture Barrier Bag provides superior drop test performance. Designed for vacuum sealing. Coded for QC traceability.
