Abstract

Layers of thermoplastic film which are not susceptible to high frequency welding may be bonded together by perforating the zones to be joined, inserting layers of a material which can be joined by high frequency welding, and welding the interlayers exposed through the holes. The interlayers are trapped by conventional welds along each border. Used esp. suitable for assembling gps. of filing pockets made of folded polyolefin or 'Mylan' (RTM-polyethylene terephthalate) film, by insertion of layers of PVC film.
