Topic: Bonding tamper-evident closures and tamper-evident labels and tax labels.
Tamper-evident labels – strong bonding on glass and metal thanks to Openair® plasma pretreatment
pretreatment of bottle and glass closures prior to labeling was one
of the earliest standard applications of the Openair® plasma Plasma
Plasma treatment for tamper-evident labeling
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).
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.
plasma Plasma pretreatment, the entire labeling of both the main
label and the seal label can be accomplished with the same adhesive.
