In the research and development stage, every waste of raw materials is an invisible consumption of budget.

One of the core values of a small blown film machine lies in its ability to complete a complete blown film experiment with just a small amount of material.

Compared to large-scale equipment, there is no need to worry about material waste. It allows researchers to boldly experiment with various new formulas and proportions.

Our Film Blowing Machine Advantages

Small does not mean crude. Excellent small film blowing machines adhere to high standards in core components:

Screw barrel

  • Made of nitrided alloy steel or dual alloy material, it is wear-resistant and corrosion-resistant. For some models, the L/D ratio can reach over 30:1, ensuring stable extrusion output and sufficient plasticization, thereby reducing crystallization and film breaks from the source.

Drive system

  •  Standardly equipped with servo motors or variable frequency speed control, enabling continuous speed adjustment. This not only saves energy and is quiet, but also allows for precise control of the rotational speed, ensuring uniform thickness of the film

Temperature control system

  • Digital intelligent temperature control, with a temperature control accuracy of ±1℃, paired with ceramic or cast aluminum heating rings, featuring fast heating and good heat retention, easily handling the processing of various materials such as PE, PP, PLA, and TPU

Mold head runner

  • The specially optimized runner corners ensure smooth melt flow without dead zones, significantly reducing material changeover and cleaning time, making it especially suitable for experimental scenarios involving frequent recipe changes

PLC control

  • The interface is intuitive and simple, with parameter settings being clear at a glance. Even operators without extensive film blowing experience can quickly get started after short-term training. It provides data acquisition functions, including temperature, pressure, and other process data, providing a quantitative basis for process optimization

Versatility

  • By replacing the die head and adjusting process parameters, the same equipment can be adapted to produce films of different colors, thicknesses, and textures using various polyethylene and biodegradable materials such as LDPE, HDPE, LLDPE, and PBAT.

 

It is not a simple miniaturization of large equipment, but a precision tool rebuilt according to real needs.

Whether you are a university laboratory exploring new materials or a small and medium-sized enterprise aiming to enter the flexible packaging field with controllable investment, a high-quality small blown film machine will serve as a solid foundation for supporting business growth.
