PKSC 4300: Testing of flexible packaging
1. Describe indicator test: include various test like PVdC, NC, acrylic, and IR to indicate the material
composition
2. Describe basis weight test: units: pound per ream
3. Describe thickness test: units: gauge, mils, or inches
100ga = 1 mil = 0.001 inches
- measures the thickness and its consistency across the web
4. Why is measuring the consistency of thickness important?: to check for possible gauge
bands in the web as it adversely affects the materials "runnability" in the machine
5. Describe surface properties test: can either measure the surface energy or COF of a material
6. Describe COF test: COF affects the functionality of a film
- Static COF is the friction for starting and stopping
- Kinetic COF is the friction of moving
- can be measured surface-to-surface and surface-to-steel
7. What is the equation for COF?: COF = friction force/normal force
8. Describe adhesion test: units: g/in
