Plasma surface treatment can also be used to improve the surface properties of plastic credit cards, such as polyvinyl chloride (PVC) or polyethylene terephthalate (PET). The treatment can enhance the adhesion of inks, coatings, and adhesives, which can improve the durability and longevity of the card.
During plasma surface treatment, the plastic credit cards are exposed to a low-pressure plasma discharge. This plasma discharge can activate the surface of the plastic, creating more polar or hydrophilic functional groups on the surface, which can improve the wetting and adhesion of inks, coatings, and adhesives.
The plasma treatment can also remove any contaminants or organic substances that may be present on the surface of the plastic credit card. This can ensure a clean and uniform surface, which can further improve the adhesion of inks, coatings, and adhesives.
Plasma surface treatment can be particularly useful for printing high-quality graphics and text on plastic credit cards. It can also improve the adhesion of magnetic stripes or chips used for electronic transactions, which can increase the durability and reliability of the card.
Overall, plasma surface treatment can be a valuable process for enhancing the surface properties of plastic credit cards, improving their functionality and aesthetic appeal.
