Definition
Film thickness specified in mils or microns; directly affects stiffness, puncture resistance, and cost.
Applications
- Specifying roll stock
- Selecting liners
- Balancing toughness vs material use
Benefits
- Improves mechanical strength when increased
- Stabilizes runnability
- Helps meet drop/abuse requirements
Industry Examples
- Medical: controlled gauge for consistent seal pressure and peel performance.
- Industrial: heavy gauge liners for bulk materials and sharp-edged parts.
- Electronics: determines puncture resistance and stiffness of MBB films protecting sharp-edged PCB assemblies.
FAQ
Q: Is thicker always better?
A: Not necessarily—structure and resin choice can outperform thickness alone.
Q: How is gauge verified?
A: Micrometers, lab measurement, and inline gauge control systems.
