EMP Faraday Bag - 20" x 30"


This Really Big EMP Protection Faraday Bag will protect full-size computers, keyboards, and other large electronics such as home stereos, DVD players and more. This EMP shield bag acts like a Faraday cage and can be used in an office, home, or vehicle to protect electronics from electro-magnetic pulse energy created by nuclear detonation over the USA.

This is not a standard Mylar bag used for food storage.  This is a MILSPEC (Military Spec) product designed for EMP shielding and protection.

The multiple layer construction on the EMP Shield Bag provides full protection against ESD, EMI/RFI and tribocharging.  There is no need to insulate the electronics before placing them in the Faraday bag. Place a cell phone or HAM radio in this bag and try to contact it and it will NOT receive the signal.

Faraday Bag utilizes the most current metalizing technology and its moisture barrier performance exceeds foil laminates for low Moisture Vapor Transmission Rate (MVTR), particularly after flexing. In other words whatever you place in the bag and seal properly is going to stay dry.
