The majority of thermoplastics have inherently low surface energy and therefore exhibit poor adhesion characteristics. Plasma treatment offers a reliable and environmentally friendly method of both cleaning and activating the thermoplastic surface, increasing the surface energy and wettability and resulting in greatly improved adhesion characteristics.
