Blown film production process and its common fault – blowing, the production process – the plastics industry
HC plastic mesh : Blown film production process and Faults
Most thermoplastic blow molding method can be used to produce blown film, blown film is extruded thin plastic tube, then hot compressed air to blow plastic inflation, then by cooling tube obtained after setting products like films, directed this film’s performance in the film between the same cast film: intensity than cast film is good, sealing of cast film worse than that. Film blowing production of many varieties, such as low density Polyethylene ( LDPE ), Polypropylene (PP) , High density polyethylene ( HDPE ), Nylon ( PA ), An ethylene vinyl acetate copolymer (EVA) and so here we are on the commonly used low-density polyethylene (LDPE) film blow molding process and a simple description of common faults.
