Product Description
BOPET Film Production Line MDO Nip Roller HNBR Rubber Coated
The MDO (Machine Direction Orientation) Nip Roller is a critical component in BOPET film production lines, where cast film is stretched in the machine direction through a three-step process.
Production Process Overview
- Preheating: Film passes through preheat rolls to acquire stretchable properties with controlled heat application
- Stretching: Film undergoes stretching via specialized rolls (smaller than preheat/annealing rolls) with nip rollers acting on stretching rolls
- Annealing: Final temperature application minimizes film relaxation for optimal product characteristics
Key Features
- Surface Quality: Precision-engineered flat, smooth, centered, and round surface ensures continuous sealing
- Durometer: Soft rubber covering conforms perfectly to film surfaces, including folded edges or gusseted films
- Air Trapping: Designed to effectively trap air within film bubbles in conventional cooling systems
- Repairable: Surface can be restored through regrinding or recovering when worn or damaged
Performance Benefits for BOPP Film
- Maintains consistent speed for optimal film quality and production efficiency
- Enhances bubble stability throughout the production process
- Prevents film defects with precision-engineered smooth surfaces
- Applies uniform pressure across the entire film width
- Facilitates defect detection with specialized nip impression films
