Abstract
A weldable and/or heat-sealable, single- or multilayer film having at least one weldable and/or heat-sealable layer, the weldable and/or heat-sealable film being provided on at least one side on one outer surface with an antistatic coating, wherein the antistatic coating has a thickness of from about 0.005 to about 0.08 .mu.m and comprises at least about 60% by weight of a soluble, intrinsically electroconductive polymer which comprises structural units of the formula ##STR1## in which R.sup.1 is a C.sub.1 - to C.sub.12 - or a C.sub.6 - to C.sub.30 -alkoxy group, and which has a degree of polymerization of less than about 100, where the polymer or oligomer is in oxidized form and has an appropriate number of anions to compensate for the positive charge. These films are heat-sealable, in spite of their antistatic coating.
