ESD shielding and moisture barrier bag PET/MET/PE, 152 x 254 mm

Moisture-sensitive devices need two barriers: one against electrostatic fields and one against water vapour. This bag in 152 x 254 mm combines both in a PET/MET/PE laminate with a thickness of 0.09 mm. It is sized for medium-sized PCBs and populated assemblies. There is enough margin in width and length to heat-seal the bag cleanly once it is filled.

Benefits

• Faraday shield: The metal layer keeps discharge energy inside the bag below 10 nJ.
• Dissipative inside and out: Surface resistance below 10E11 Ohm on both sides.
• Moisture protection: The film has a defined water vapour transmission rate and can be vacuum packed.
• Sealed shut: The bag is heat-sealed, so any opening is visible at once.
• Clearly marked: Printed ESD warning symbol, compliant with EN 61340-5-1 and RoHS.

Applications

The bag is used to store and ship medium-sized PCBs and populated assemblies outside the EPA. It is usually filled together with desiccant and a humidity indicator card, then vacuum packed and heat-sealed. The range is available in other formats as well.
