Welding of polyethylene. Polyethylene does not stick to any glue. Polyethylene films can be easily welded, pinching the edges between two flat wooden or metal strips, so that the edge of the 1-width foil protrudes…1,5 mm. Then slide from the bottom, along the protruding edge, a small flame of a candle, at such a distance, that it melts the edge of the foil, but he didn't light it. With some skill, you can obtain welds that are not inferior in strength to welds obtained on special welding machines. Welding with this method of PVC foil is also possible, but gives worse results.
