Lab Scale Blown Film Plant: High-Performance Lab Film Blowing Machine & Blown Film Extruder 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.


What Makes Our Lab Scale Blown Film Plant Stand Out?


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.


Core Advantages of Our Lab Film Blowing Machine & Blown Film Extruder Machine


  1. Precision Control: The entire lab scale blown film plant adopts closed-loop control technology, with the blown film extruder machine and

  2. 1. lab film blowing machine working in sync to achieve precise control of film thickness (tolerance ±0.005mm) and width. This level of accuracy

  3. is crucial for R&D projects that require repeatable test results.

  4. 2.Compact & Energy-Efficient: Designed for lab spaces, the plant has a small footprint (usually 1.5m×1.2m×2.0m) and low power consumption

  5. (1-3kW), making it suitable for limited laboratory environments. The air-cooled cooling system of the lab film blowing machine further reduces

  6. energy usage and operational noise.

  7. 3.Versatile Compatibility: Our blown film extruder machine supports a wide range of plastic materials, including polyethylene (HDPE, LDPE),

  8. polypropylene (PP), polyvinyl chloride (PVC), and bio-based polymers. This versatility allows researchers to develop diverse film products, from

  9. packaging films to functional membranes.

  10. 4.Easy Maintenance & Safety: All components of the lab scale blown film plant are modularly designed for easy disassembly and cleaning. Safety

  11. features such as over-temperature protection, emergency stop buttons, and protective covers ensure safe operation in the lab.


Applications of the Lab Scale Blown Film Plant


Our lab scale blown film plant—equipped with a high-performance lab film blowing machine and blown film extruder machine—is widely used in:

  • lResearch and development of new plastic materials (e.g., biodegradable films, high-barrier films)

  • lProcess optimization for industrial-scale blown film production

  • lSmall-batch production of special-purpose films (e.g., medical packaging films, agricultural mulch films)

  • lQuality control and performance testing of plastic films (e.g., thickness uniformity, tensile strength, barrier properties)


Why Choose Our Blown Film Extruder Machine & Lab Film Blowing Machine?


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.
