Inkjet printing is widely used on various types of plastic products, from 3C electronic devices and automotive components to films, plastic packaging bags, food containers, and various injection-molded parts. Inkjet printing technology can meet all kinds of printing needs. From simple text, letters, barcodes, QR codes to astonishing high-quality full-color graphics, inkjet printing can easily achieve high-adhesion printing effects.

To optimize adhesion before the inkjet printing, surfaces of products are subjected to pre-treatment processes like plasma and corona treatments. These techniques bolster the UV ink's adhesion longevity, ensuring a superior degree of adherence. Manufacturers can tailor the pre-treatment to the specific adhesion needs of their products, selecting the most suitable method. Substrates that receive corona treatment benefit from augmented characteristics, including enhanced corrosion and wear resistance, contributing to the overall durability of the product.

Not all substrates require corona treatment. Corona treatment technology varies for different materials. Typically, materials with non-polar structures necessitate corona treatment, which involves the oxidation and polarization of surface molecules, activating the surface to enhance the substrate's adhesion capability. This is precisely why inkjet printers are equipped with a corona treatment stage.
