DESCO’s Impregnated Corrugated Material has a dissipative surface minimizing the level of energy discharge to an ESD sensitive product and has the discharge shielding performance equal to a Metal Out Static Shielding bag when lid is in place, coated boxes do not. Also, their Impregnated Corrugated material can withstand the rigors of transportation and continuous use making them potentially the least expensive ESD packaging choice over time. This also makes it the perfect choice for returnable packaging, saving valuable time and money.
