A Corona Treater is often used in woven sacks printing machines to improve the adhesion of inks to the woven sack material. Woven sacks are made from a variety of materials, including polypropylene (PP), polyethylene (PE), and other plastics, and can be difficult to print on due to their low surface energy.
The Corona Treater used in a woven sacks printing machine works by generating a corona discharge that ionizes the air between the electrode and the woven sack material. This ionized air reacts with the surface of the woven sack, creating polar groups on the surface of the material. These polar groups increase the wettability of the woven sack and improve the adhesion of inks to the material.
When selecting a Corona Treater for a woven sacks printing machine, it is essential to consider the width and speed of the material, as well as the type of material being treated. It is also crucial to choose a Corona Treater that can provide consistent and repeatable treatment results to ensure that the inks adhere properly to the woven sack material. The Corona Treater should also be designed to withstand the harsh environment of a manufacturing plant and offer flexibility in treatment settings to optimize the adhesion of inks to the woven sack material.
