An antistatic sheet or bag for electrostatic sensitive devices is obtained by uniformly mixing a thermoplastic polymer such as polyethylene with about 0.1 to 0.7 per cent by weight of an antistat, extruding the mixture in the form of a tubular sheet, subjecting the sheet to a corona discharge, printing on the sheet or both sides of a tube forming said sheet, with a carbon conducting ink, cutting the sheet into units of desired length and sealing the end of each such cut unit to form a bag.

An antistatic sheet for the rapid dissipation of an electrostatic charge, said sheet comprised of a thermoplastic polymer selected from the group consisting of polyethylene, polypropolyene and copolymers of ethylene and propylene, said polymer having uniformly distributed therein from about 0.1 to about 0.7 percent by weight of an antistat selected from the group consisting a tertiary amine, an anionic phosphate ester a quaternary ammonium halide, and a sulfonated aliphatic hydrocarbon, said sheet having been subjected to a corona discharge and having an imprint of carbon conducting ink thereon adapted to rapidly dissipate an electrostatic charge.
