Hot melt filter bag process
Hot-melt filter bag is called high-precision PP wireless seam filter bag, and there are a variety of production processes, such as: steel ring full welding, plastic ring full welding, plastic ring full welding, steel ring full welding, bottom seam seam ring mouth welding, bottom seam welding ring mouth seam, ribbon wrapping, reverse seam, etc.
Hot melt filter bag produced by imported material with high purification of filament fiber needled felt, filtrate filter out special singeing process on the surface, all the raw material is this white, without any special bleaching processing, full compliance with environmental standards, effective against pollution of the filtrate of fibers, high strength of long fiber filter bag filter efficiency stability, long service life.
The ring mouth, bottom and sides of the hot-melt filter bag are seamless, avoiding the pinhole caused by sewing the filter bag. Hot-melt welding method is adopted to ensure the strongest and consistent welding at each point. It is suitable for the field with higher accuracy requirement. Ensure the filter bag is not affected by other production accessories, ensure the consistency of each filter bag material.
