Polypropylene extrusion blown film, like polyethylene blown film, is a versatile and versatile film. Polypropylene blown film is the lightest, non-toxic, and has good mechanical properties, transparency, and heat resistance. It can be cooked at high temperatures of 100 ℃ without deformation. Polypropylene blown film is mainly used for packaging various items, especially suitable for various clothing and food packaging applications.
The production process sequence is as follows.
Polypropylene resin ->Single screw extruder plasticizes and melts raw materials ->Forming mold extrudes tubular film blank ->Pulling machine pulls the film blank to run (at the same time, the film drum is blown into film bubbles, cold air blowing or water cooling is used to shape the film) ->Pulling device ->Drying ->Corona treatment (depending on the purpose) ->Finished film winding
