The 70056 is an aluminized moisture barrier bag designed to protect ESD and moisture-sensitive components. It is manufactured from a multi-layer laminate of aluminized polyester and polyethylene with a thickness of 3.6 mils, providing puncture resistance of 20 lbs and ESD shielding of less than 10 nJ. The bag features a very low moisture vapor transmission rate (MVTR) of less than 0.035 grams per 100 sq. in. per 24 hours and offers 45 dB of EMI attenuation. These heat-sealable bags are suitable for vacuum packaging and are ideal for protecting sensitive electronics during storage and transport.
