HERMA will highlight its new HERMAsuperPerm 63S adhesive — which makes labels tamper evident — at the LabelExpo 2015 exhibition, on 29 September–2 October 2015, in Brussels, Hall 11, Stand C40. Such tamper-proof features will become mandatory for prescription drugs according to EU directive 2011/62/EU.
The adhesion of HERMAsuperPerm 63S is so strong that labels equipped with the adhesive cannot be removed from lacquered pharmaceutical packaging as well as many other polar and non-polar surfaces, such as paper, cardboard or plastics and steel, without destruction of the label or the packaging surface. Elaborate and costly special materials like self-destructive films, holograms, cellophane wraps or even completely new folding box designs are thus no longer required.
HERMA superPerm 63S is also highly resistant against water, hot air and various solvents. Since it is a dispersion adhesive, adhesive materials can be easily processed in spite of relatively thick adhesive coating.
A number of reasons can be argued for the use of sealing labels to ensure a first-opening guarantee: “Labels on pharmaceutical packaging are, as a matter of principle, accepted in the market. Moreover, they do not change the established appearance of existing packages," explained Dr. Ulli Nägele, HERMA’s head of development. “Folding boxes and folding box machines that have already been validated can continue to be used.”
The application process for the labels, which have an essentially conventional design, is technically uncomplicated. “The main reason against using conventional, economic labels for reliable tamper-proofing was the fact that they are removable. This has been invalidated through HERMAsuperPerm 63S.”
Initially, HERMAsuperPerm 63S is available with white, semi-gloss coated paper (HERMAextracoat, grade 242, or HERMAsuper 60, grade 232) or with a transparent, glossy polypropylene film with a topcoat (HERMA PP 50, grade 885). If required, other label materials such as paper with security features can be used.
