Adding the carbon layer is state of the art technology and added during the 6 layer paper making process. The top layer is static dissipative 1 x 10⁶ - 1 x 10⁹ ohms. The conductive carbon layer is the 5th layer from the surface 1 x 10⁴ ohms. Burying the conductive layer under a static dissipative surface reduces the potential for rapid discharge when in contact with a charged device. The material is also manufactured by one paper mill using computerized controls which ensures consistent quality. The Impregnated Corrugated material has greater durability than a coated material. Abrasion tests show no loss in particles at 100 cycles, while the coated material shows a 50% loss in particles in only 10 cycles. Because the shielding layer is built into the corrugated material, the boxes will maintain a quality appearance much longer than a painted or coated product. The material will not flake to reveal the brown, Kraft corrugated material underneath.
