Corona Treatment is a well known process used in the extrusion and converting industries. Corona treater electrodes, roll coverings and power supplies can be optimized to meet the challenges of printing, coating, laminating, blown film, and cast film applications. Below is a sampling of typical applications where corona treatment is used to promote adhesion.
Improve Ink Printing Adhesion with Surface Treating
The task of optimizing printing adhesion can be difficult, primarily because of the many process variables which require control. There are six major printing/decorating processes, each distinguished by the method in which ink and an image are transferred to a substrate, and by the method by which the ink and image are conveyed for adhesion to a substrate. Almost all surfaces require preparation to establish minimum adhesion requirements. This step is known as pretreatment and post-treatment, and influenced by the base material surface receptivity of the ink layer.
