Static Shielding Bag (SSB)

SSB is manufactured by depositing a thin metal coating, like aluminum over an antistatic polyester film substrate. This metalized layer protects the devices or the components in the bag from electrostatic fields. According to the position of the metalized layer, there are two types of metalized shielding bags, “Metal-In” and “Metal-Out”, in the market. A metal-in bag or a buried metal shielding bag is the most commonly used and recommended for packaging of static-sensitive components. It also tends to be superior to a metal-out bag in durability and cost. A metal-out shielding bag also protects the devices in the bag against static-induced damage. As the me tal layer is closer to the outside surface, the metal-out shielding bag has lower ESD reading than a metal-in bag. The SSB we offer is a metal-in type, which has the metalized layer inside.
