Corona Treatment
Can you tell me what it means to corona treat a tape product?
Corona treatment is is an interesting process that alters the surface of a material and essentially its surface energy. The material is exposed to a high voltage electrical discharage during the corona process, which causes the change to occur. This treatment is typically used to raise the surface energy of films such as polyethylene or polypropylene to obtain better adhesion of inks, adhesives and other coatings. High energy surfaces allow better wet-out of the coating than those with low surface energy.
