CP BLACKSTAT is constructed from polyethylene impregnated with compressed carbon to protect sensitive electronics and explosive devices susceptible to sparking. Its multilayer construction will also protect against abrasion, ultraviolot light, and moisture if heat sealed. This material is non-abrasive and non-contaminating. Because this film is extruded with resin containing E.V.A., it exhibits excellent puncture and tear resistance along with a good seal integrity.
