From February 2019, all pharmaceutical packaging of
prescription medicines in the EU must include a tamper-evident closure as a
security feature. This is stipulated by the EU Directive 2011/62/EU adopted in
2011. In order to continue to use the existing folding boxes, the use of
sealing labels is of particular interest in terms of cost-effectiveness. These
labels firmly connect the insertable tags to the body of the package. The most
practical labels from an economic and technical point of view are completely
conventional rectangular or round labels. These labels may even include a
security perforation. The essential factor for their use is the
pressure-sensitive adhesive. It must be highly resistant to water, hot air and
various solvents. This is the only way to guarantee that the label cannot be
peeled off even heavily coated folding boxes without visibly destroying either
the label or the box. The same type of sealing label can therefore be used for
a variety of packaging materials and for a variety of surfaces – even hot
melt-sealed boxes can be protected against tampering using this method.
The use of tamper-evident labels requires a high degree
of precision. This is because the labels, which are usually very small, must be
applied laterally to the insert-able tags in such a way that around 50 percent
of the label protrudes above and below the body of the folding box.
