Common Packaging Polymers
- Application properties and common applications of the polyethylene family
- Application properties and common applications of:
- polypropylene, polystyrene, poly(vinyl chloride)

Property Comparisons
- Values provided are for establishing relative orders
- They do not refer to any specific product
- Many resins offered as polymers are actually copolymers
- Polymers may be heavily modified with additives
- No two polymer producers manufacture identical resins
- Therefore values for commercially available resins can vary significantly from the example values
