CAPSTM is a modern plasma technology system for the specific modification and fictionalization of web surfaces, with the goal to make expensive and sometimes environment unfriendly surface coatings redundant, and at a fraction of the running costs and capital investment. As CAPS™ is based in many aspects on the proven corona technology; it can do so with the reliability and ease of use of this well known and long proven pretreatment method.


How does it work?

CAPSTM is based on a plasma discharge in a precisely controlled gas atmos­phere at atmospheric pressure. It can result in extremely high level adhesion based on chemical bonding, rather than physical adhesion thanks to surface tension increase, and on various polymer films such as BOPP, cast PP, BOPET, PE, PVC, and many others. Other than corona treatment, these excellent adhesion properties can also remain for a very long time under good preconditions.


Applications of CAPS

CAPSTM is the ideal platform for the advanced atmospheric pressure plasma, allowing innovative coating and converting companies to utilize our ex­pertise in using technical gases to specifically modify film surfaces. The combination of this unique Know-How and Plasmawerk’ CAPS™ technology will guarantee perfect ad­hesion at minimal cost.
