Modern packaging take on new responsibilities by the advent of new technologies and materials. Fighting against product piracy or protection from improper use are examples that show requirements. Self-adhesive labels are more and more used as an effective first-opening protection. The pharmaceutical industry aims for safety in cartons - the chemical industry even more.
An example for screw caps:
By pretreatment with Openair-Plasma® the labels sticks on small diameters and tight radii. Even critical areas at the beginning and end label stick optimally. The label sits absolutely tamperproof.
The mechanical and electrical integration of the system by Plasmatreat is simple: The pretreatment of closures happening OFF-Line or in-line, directly and as part of the labeling. The pretreatment of the surface is thus part of the process and offers product and customer safety.
