High Speed Biaxially Oriented Stretch plastic Film Roller, High Dynamic Balancing Accuracy plastic Film extrusion Roller for Bi-Oriented Stretch Film Production Line
Related Information：Application of Suzhou Jwell High-speed Rubber-coated Rollers in Biaxial Stretching Film Equipment
1.Function
These rollers from Suzhou Jwell are used in the production of bi-oriented stretch films, helping to stretch the film biaxially (in both machine and transverse directions) to enhance its strength, clarity, and barrier properties.
2. Design
- Precision Engineering: Designed for precise control of film stretching to ensure uniform thickness and consistent film properties.
- Surface Finish: Highly polished surface to prevent sticking and ensure smooth film movement.
- Temperature Control: Often equipped with heating or cooling systems to manage the film's temperature during the stretching process.
