Abstract
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.
