The PP blown film machine is suitable for the production of polypropylene (PP) plastic film, widely used in food, clothing, textiles, daily necessities and other civilian products and industrial supplies packaging.
Contact us and get PP blown film making/extrusion machine!
The die head can choose 360 degrees of rotation, can enhance the strength and uniformity of the plastic film.
The screw and material cylinder are made of 38CRMOALA alloy steel, through nitriding treatment and precision processing, high hardness, strong corrosion resistance, durable.
Die head coated with hard chromium, its structure is spiral mandrel type, uniform molten material and good film finish; air cooling device is labyrinth structure with uniform air volume. The circulating water is used to achieve good transparency.
The winding device adopts pressure friction or central winding, adjusted by torque motor, smooth winding and easy roll changing.

Using polypropylene (PP) as the raw material, the PP Blown Film Machine delivers films with excellent clarity, gloss, and high-quality surface finish — making it perfect for packaging where visual appeal and printability matter.
PP films produced on this machine also offer strong mechanical strength, tear and puncture resistance, and good chemical resistance, which means the finished packaging can handle demanding usage — whether for food, consumer goods, textile packaging, or industrial materials.
Because PP has a relatively high melting point and better heat resistance compared with many common plastics, the films are more stable under higher temperatures, making them suitable for packaging items that face heat or require sterilization.
This PP Blowing Machine is designed for efficient, high-speed production with consistent film quality. Advanced extrusion and cooling systems ensure uniform thickness, smooth surface, and reliable output — which helps manufacturers meet high-volume demands while keeping waste and downtime to a minimum.
Finally, films made from PP are often lighter and easy to recycle, offering a balance of performance, cost-effectiveness, and environmental friendliness — a major advantage for packaging producers aiming for sustainable, high-quality solutions.
