Coefficient of Friction: The Quiet Driver of Packaging Line Performance
2025-12-22
Coefficient of friction rarely appears on a marketing sheet, but it decides whether film feeds smoothly or jams.
Why it matters
- High friction causes drag, misfeeds and film stretching
- Low friction can cause slipping and misaligned registration
- Consistency across the roll matters more than any single value
How it is controlled
- Measured on dedicated friction testers, on both faces
- Set by formulation and surface treatment during film making
- Verified per batch, with records available on request
