Abstract
A welding tool for welding plastic films, with a carrier part that has a mechanical interface for coupling to a welding device and with a support surface. At least one recess is formed in the support surface, which recess is fluidically connected to a fluid channel in the carrier part, and with a heating band arrangement which rests on the carrier surface and includes an electrically conductive heating band which is accommodated between an electrically insulating base layer and an electrically insulating cover layer. The base layer is provided with an opening which covers the recess at least in some areas.
