Types of Polymers Used in Commodity Packaging

In this Chapter, the types of plastics that are being used in these applications are briefly reviewed. The variants of these polymers such as copolymers and blends are discussed together with a brief general discussion of the properties of the polymers which are most relevant from the point of view of their use in applications involving

The principles covering the design of extraction tests proposed by various authorities are reviewed in Chapter 1. Chapters 2 and 3 review the types of polymers and elastomers, respectively, used in the packaging and the types of deliberately added or adventitious compounds that can occur in plastics and can be extracted into the packaged commodity. 

There are many types of plastic materials with a range of properties that depend on the base polymer and the additives used. Plastics are used routinely in many commodity items such as packaging, pipe, clothing, appliances, and electronics. They are also increasingly being used in structural and engineering applications such as aerospace, building, and automotive.
