The blown film machine is a core specialized machine in the plastics processing industry for producing plastic film, belonging to the extrusion molding category of plastic machinery. It can process thermoplastic plastic granules such as polyethylene, polypropylene, and polyvinyl chloride into flat, uniform, and continuous tubular plastic films through a series of continuous automated processes including heating and melting, extrusion, blowing, cooling, traction, and winding. It is an indispensable basic production equipment in industries such as packaging, agriculture, and daily necessities.
The vast majority of plastic bags, express delivery packaging films, agricultural greenhouse films, food preservation films, and industrial stretch films on the market are processed by blown film machine production lines. With its continuous production, low cost, and good film forming effect, it has become one of the most widely used equipment in the plastic flexible packaging industry.
