Lab Small Mini Plastic Film Blowing Machine
For laboratories, research institutions, and small-batch production enterprises engaged in plastic film R&D and process optimization,
a reliable lab scale blown film plant is an indispensable core equipment. Our integrated solution combines a precision-engineered
lab film blowing machine and a high-efficiency blown film extruder machine, designed to meet the strict requirements of material
testing, product development, and process verification in the lab environment.
Our lab scale blown film plant is a compact, integrated system that integrates all key components of the blown film process—from the
core blown film extruder machine to the die head, cooling system, traction unit, and winding mechanism—while maintaining the flexibility
and adjustability required for experimental operations. Unlike industrial-scale equipment, this lab-grade plant is optimized for small-volume
production (typically 1-5kg/h), allowing researchers to test new plastic formulations, adjust process parameters, and evaluate film performance
without wasting large amounts of raw materials.
At the heart of the system lies our advanced blown film extruder machine, featuring a precision screw and barrel designed for optimal plasticizing
efficiency. The screw (with a diameter range of 16-25mm and length-diameter ratio of 28:1) ensures uniform melting of plastic particles, while the
electric heating system with ±1℃ temperature control accuracy guarantees stable processing conditions—critical for consistent film quality in R&D.
Whether processing PE, PP, PVC, or biodegradable materials, the blown film extruder machine adapts seamlessly to different material properties,
providing reliable data for material performance analysis.
Complementing the extruder is our user-friendly lab film blowing machine, equipped with an intelligent control system powered by Siemens PLC
and a touchscreen interface. Operators can easily adjust extrusion speed, die head temperature, cooling air flow, and traction tension, all while
monitoring real-time data to optimize process parameters. The traction roller, with a hard-chrome plated and mirror-polished surface, ensures
smooth film feeding, while the constant-tension winding system prevents film wrinkling and ensures neat winding—essential for accurate thickness
and tensile strength testing.
Our lab scale blown film plant—equipped with a high-performance lab film blowing machine and blown film extruder machine—is widely used in:
We understand that lab-scale R&D requires equipment that is both reliable and flexible. Our lab scale blown film plant is
engineered with decades of experience in plastic extrusion technology, ensuring consistent performance and accurate test data.
The blown film extruder machine uses high-quality wear-resistant materials for the screw and barrel, extending service life and
reducing maintenance costs. The lab film blowing machine’s intuitive control system minimizes training time, allowing researchers
to focus on innovation rather than equipment operation.
Whether you’re developing a new film product, optimizing a production process, or testing material properties, our lab scale blown
film plant provides the precision, versatility, and efficiency you need. Contact us today to learn more about how our lab film blowing machine and
blown film extruder machine can support your R&D goals.
