What is Corona Treatment
Corona treatment (sometimes referred to as air plasma) is a surface modification technique that uses a low temperature corona discharge plasma to impart changes in the properties of a surface. In order words, Corona Treater is an equipment which be used for surface pre-treatment, however, the effects of corona treatment diminish over time. Therefore many surfaces will require a second “bump” treatment at the time they are converted to ensure bonding with printing inks, coatings, and adhesives.
The Difficulty Of Writing Or Printing On Plastic Film Is Well Known
As you already known, printing on plastic film is difficult process. Imaging that you want write something on a plastic bag with a pen, but the ink doesn’t stick to the surface due to the untreated plastic has a structure and this makes for poor adhesion. Corona treatment is the solution to this well known problem
Fight Against On The Poor Adhesion of Corona Treater
A well designed Corona treatment equipment is able to provide sufficient wetting and adhesion on plastic film or metallic foil at pre-treatment stage before printing, laminating or coating takes place. As one of sophisticated corona treater supplier in America, ISI has abundant experience and know how to help you to avoid the adhesive issue when selecting the corona plasma equipment, we can assist you to measure surface tension accurately and consistently among different plastic materials, and also we will help you to clarify the gettability gap for the material that you are about for applying the proper power density.
