PKSC 4300: Materials Overview Exam
1. How can materials be classified?: - broad material type
- function in a package
- material form used
- location on package
- location on the machine
2. What are the broad material types?: - polymer
- metals
- ceramics
- composites
3. Explain a material function in a flexible package?: - each layer has a one or multiple
functions
- can be strength layer, ink carrier layer, barrier layer, sealant layer, or an adhesive layer
4. describe the strength layer: - provides the stiffness which is important for how we interact with the
product
- can also add puncture, tear, and burst resistance
5. describe the ink carrier layer: - this layer must be able to be printed on; it must be wettable and
function in a printing machine
