PP 5 Times Biaxial Stretcher For Polymer Films

     Our PP 5 Times Biaxial Stretcher For Polymer Films is a specialized piece of equipment designed for the production of high-quality polypropylene (PP) films through the biaxial stretching process. With a 5-fold stretching ratio, the machine achieves uniform stretching in both longitudinal (MD) and transverse (TD) directions, effectively improving the mechanical properties, transparency, and barrier performance of PP films. It is widely used in packaging, electronics, automotive, and other industries that require high-performance polymer film materials.​

• Equipped with a touch all-in-one control system and humanized structural design for greatly enhanced operational convenience.
• Configured with a bidirectional high-performance servo motor drive, supporting one-way/bidirectional variable-speed stretching modes to meet diverse experimental requirements.
• Compatible with multiple stretching modes including one-way constrained, one-way unconstrained, bidirectional synchronous and bidirectional asynchronous stretching, adapting to different experimental scenarios.
• Fitted with multiple sets of PID precise temperature control points for higher temperature control accuracy, more comprehensive coverage and more realistic data matching actual experimental working conditions.

 

 

POTOP's PP 5 Times Biaxial Stretcher For Polymer Films, a multi-functional piece of equipment integrating R&D and production, is trusted by customers in the high-end film industry, laboratory research institutions, and other sectors. Key application areas include:

1. Packaging Industry

   A primary application area for biaxially oriented polypropylene (BOPP) film. This stretching machine produces high-transparency, high-toughness BOPP film, widely used in food packaging (snack bags, candy wrappers, cigarette packaging), pharmaceutical packaging, daily chemical packaging, and flexible packaging.

2. Electronics and Optoelectronics Industry

  Used for producing precision optical films, capacitor films, and lithium battery separators. Biaxially oriented PP film possesses excellent dimensional stability, high insulation properties, and uniform thickness, making it suitable for mobile phone screens, display panels, capacitors, and lithium-ion batteries (as a separator to prevent short circuits).

3. New Energy Industry

  Biaxially oriented PP film exhibits excellent weather resistance, high-temperature resistance, and corrosion resistance, protecting solar panels from harsh outdoor environments and ensuring the safety and stability of lithium batteries.

4. Laboratories and R&D Institutions

  Suitable for materials research and process optimization in universities, research institutes, and corporate R&D centers. This stretching machine can simulate industrial production conditions, providing reliable experimental data on the mechanical properties, crystallinity changes, and microstructure evolution of polymer films under different stretching parameters (stretch ratio, stretching speed, stretching temperature).

5. Other Industrial Fields

  Used for the production of automotive interior films (wear-resistant and flame-retardant), architectural decorative films (weather-resistant and heat-insulating), and medical packaging films (high biocompatibility and barrier properties).
