Course 2

June 20-22, 2017


Introduction to Polymers, Rigid & Semi-Rigid Plastics, Flexible Packaging, Design Basics for Plastics



Get to know polymers and plastics from their base elements to their most complex integrated applications. Polymers are designer products formed and formulated with specific attributes. They are a diverse and adaptable raw material.


Learning objectives:

• Polymer terminology

• Properties based on molecular structure & weight, density, polarity and thermal history

• Physical and barrier properties based on class of polymer

• Materials, processes and applications in moulding and sealing

• Applications of metalizing

• Closure applications

    • Monomers, homopolymers and copolymers

  • Polymer Chemistry for Non-Chemists

    Factors influencing a polymer's properties

    Properties related to molecular weight and polarity

    Polymers related to polymer crystallinity

    Tg Tm and properties imparted by thermal history

    Properties imparted by mechanical history

    • Viscoelastic properties

  • Common Packaging Polymers

    • Application properties and common applications of the polyethylene family

    Application properties and common applications of:

    - polypropylene, polystyrene, poly(vinyl chloride)

    - poly (ethylene terephthalate) and polyamide

    Application properties of polymers used as coatings

    • Comments on sustainable and selected lesser used polymers

  • 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

    • Extrusion-blow moulding:

    bottles, and other narrow-mouth containers, jars, box and drum liners, handleware, multi-layer containers

    • Injection-blow moulding:

    bottle and other narrow-mouth containers, wide-mouth jars, precision finish containers

  • Blow Moulding Plastic
