Hot-air welding

Polypropylene is welded with hot air on a modern machine which allows the welding of parts up to 50 cm wide. The weld length can be up to 90 cm. Hot-air welding is very productive, the weld is almost invisible and very clean. Given the fact that there no need to use any additive materials (adhesives etc.) this type of PP binding is environmentally-friendly.
Polypropylene can be welded in a thickness range from 0.40 mm to 0.80 mm.
