PKSC 2020 Test 1 - Fall 2025
1. ------------------Manufacturing Definitions Slides ----------------------: -
2. Manufacturing definition: Making products from raw materials by various processes, machinery, and
operations, following a well-organized plan
3. 5 packaging materials:: Paper, Plastic, Steel, Aluminum, Glass
4. Factors that affect raw material selection: service life, cost, availability, domestic and interna-
tional issues (geo-political, weather), state laws
structural, mechanical, physical, & chemical properties of the final product
5. Raw materials are " " into polymers, substrates, etc.: converted
6. 3 levels of structure considered in packaging:: Atomic, Microscopic, Macroscopic
7. Mechanical properties:: tensile, elongation, elasticity, creep, dimensional stability, etc.
8. Physical properties:: density, specific heat, electrical and magnetic, melting point, etc.
,9. Chemical properties:: oxidation, corrosion, leaching, general degradation
we don't want reactions to occur with product or environment
10. Visual properties:: gloss, clarity, transparency, haze, etc.
11. ------------------ Wood and Pulp Industry Slides ----------------------: -
12. The physical structure of wood affects:: harvesting, pulping, paper manufacturing process,
paper characteristics (ex. strength and printability)
13. Raw material in paper: cellulose pulp
14. Tree bark & wood processing:: - bark is considered an impurity
- fibers are too small
- shows as specks in paper
- can be used as fuel
15. Wood properties:: 1. Moisture content: percentage of water
2. Specific gravity: the density of wood material
3. Tension and compression strength properties
4. Bark content
, 5. Chemical composition: cellulose, hemicellulose, lignin, and extractives
