Abstract

A method for producing a tight joint between a multi-layer synthetic resin material and a filter medium by selectively melting a layer of the synthetic resin material which has a different thermal absorption capacity in comparison with the other layers by heating the synthetic resin material with infrared radiation, and then fusing the melted synthetic resin layer to the filter medium. A filter element produced by the method of the invention is also disclosed.
