Packaging Out: The Last Metre of ESD Control
Match the bag to the risk
Static shielding bags with a conductive metallised layer protect against both direct contact and external static fields; dissipative bags prevent charging by contact but shield poorly. For boards and modules leaving the building, shielding bags are the default.
Parts should be inside the bag with the flap fully closed; a bag is not a pouch, and an open top defeats the shield.
Cartons and labels
Ordinary cardboard is fine as outer packaging because it is not a tribocharging hazard at the levels that matter; keep the ESD protection at the inner layer. Apply ESD warning labels on the outer carton so receiving and customs handlers know sensitive goods are inside.
FAQ
Is bubble wrap safe for ESD parts?
Regular bubble wrap charges strongly when rubbed; use dissipative or conductive bubble products for sensitive items.
Can I reuse shielding bags?
Yes if the metallised layer is intact and the bag is clean; crinkled, torn or delaminating bags go to scrap.
Do I need ESD labels on every carton?
Label cartons that contain ESD-sensitive goods so downstream handlers treat them accordingly; it also simplifies receiving inspection.
What about humid climates?
Humidity reduces charging but is not a control. Keep the same bagging discipline regardless of season.
