2100r 3m 2100R 3M The transparent, puncture resistant metal-out static shielding The transparent, puncture resistant metal-out static shielding bag is designed to provide a static safe environment for sensitive electronic devices. The metal layer is positioned near the outer surface to help reduce voltage retention and enhance static decay. Bags are printed with and ESD warning symbol and a lot code for traceability. open top 12 inch x 16 inch. The bags are heat sealable. 3M Static Shielding Bags are manufactured from a top coat, metal, polyester, polyethylene laminate. The proprietary top coating is designed to protect the metal layer. Polyester dielectric, in concert with the metal layer, is intended to provide shielding of Electrostatic Discharge (ESD) and to help minimize the penetration of electric field. The bags are tested to meet or exceed certain electrical and physical requirements of ANSI/ESD S541 and to be ANSI/ESD S20.20 program compliant. Bags are RoHS Compliant* and lead-free 210216
