Tamper-evident labels – strong bonding on glass and metal thanks to Openair® plasma pretreatment

Plasma pretreatment of bottle and glass closures prior to labeling was one of the earliest standard applications of the Openair® plasma Plasma process.
 Plasma treatment for tamper-evident labeling
To ensure the integrity of a package’s contents, a tamper-evident closure or tax label is required. These seals must be glued from the main label (on glass) up over the closure (metal or plastic).
The closures that are used are produced in a cold forming process that uses lubricants that can leave remnants residues on the surface of the closure that require micro-cleaning prior to adhesiongluing.
After Openair® plasma Plasma pretreatment, the entire labeling of both the main label and the seal label can be accomplished with the same adhesive.
