Today we are talking films on Tech Talk ― as in corona treatment of ― not the latest “must- see” summer blockbuster (although we enjoy those, too!). So what do you need to know about corona treatment and successful treatment of films?
As you probably know, corona treatment can help you modify plastic films and other materials to render them more bondable, or to provide a longer lifespan. Corona plasma is a visible electrical discharge which is produced when a high-voltage and high-frequency electric potential comes in close to electrodes in the atmosphere. When the discharge occurs, ions and ozone are generated; the ozone compound is relatively short-lived and may dissociate to molecular oxygen (O2) and oxygen radical (O`). The oxygen radical then works to modify the polymeric film material. Explore corona treatment and other techniques in the Surface Modification Technical White Paper.
While corona treatment has a very-high success rate, there are three common challenges to be aware of:
Beyond film, corona treatment is also applied to other in-line processes such as foils, paper, webs and tape. Will it work for your materials? Fill out a Surface Modification Worksheet with your design specs and we’ll help you find out!
