Low thermal conductivity weldable pack - has areas coated with weldable polymer which incorporate material absorbing HF energy and heat up in applied field

摘要

A pack is made of material which is a poor conductor of heat and has parts where plastic material can be welded together. Those parts are treated or coated with a material which absorbs, (pref.) h/f energy and is pref. a ceramic of oxides of their compounds. ADVANTAGE - The packing material can be welded together with inexpensive equipment but without needing conducting coatings or the direct application of welding pressure tools.
