Used in various industries in containers, packaging electric appliances, automobiles, and pharmaceuticals, plastics are staple of daily life. Compositions range from single materials to composites.

We measured the inner surface potential of various plastic containers: polyethylene (PE), polypropylene (PP), tetrafluoroethylene-perfluoroalkyl vinyl ether copolymer (PFA), and polyethylene terephthalate (PET).
