Abstract
Capsules, for example for the delivery of pharmaceuticals, are produced from at least three films () of a water-soluble polymeric material, by deforming two of the films () to form a multiplicity of recesses, and filling the recesses () with a flowable filling material. A film () is used to cover the recesses () in at least one of the films (), and is welded to it by dielectric welding. The films with filled recesses are then brought together and welded together by dielectric welding to form filled capsules, which are cut or punched out of the welded film. The polymeric material may be gelatin, or a water-soluble cellulose derivative such as hydroxypropyl methyl cellulose, and may also contain a plasticiser.
