Abstract
A molded synthetic-resin container having a wall with an outer surface has a layer of conductive particles imbedded in at least a portion of the wall at the outer surface thereof. This layer is made according to the invention, after blow-molding of the container, by heating and thereby disrupting a surface region of the container, then applying a conductive powder to the disrupted surface region, and finally heating the powder on the disrupted surface region and sintering it into the disrupted surface region.
