Tamper-evident labels for packaging

Seal as proof for authenticity, according to EU Directive 2011/62/EU

Starting in February 2019, all prescription medicines sold in the EU must have a seal that serves as proof of authenticity, among other safety features. This is a provision of EU Directive 2011/62/EU, which was adopted in 2011, supplemented by the delegated regulation (EU) 2016/161/EU. From the cost-benefit point of view, sealing labels are an especially interesting way to continue using folding boxes that are already in use. These safety labels permanently affix the tuck-in flap to the body of the box.

Flexible and pliable – for reliable application

In terms of economic viability and technical practicality, conventional rectangular or round labels, preferably with additional security perforations, are the best solution. The label material, which is usually transparent PE or PP film, is especially flexible and pliable – ideal for labelling around corners. The adhesives are highly resistant to water, hot air and a variety of solvents. Only if these conditions are met is the label impossible to peel off, even from highly varnished cartons, without either being destroyed or visibly damaging the surface. For especially difficult surfaces, special adhesives are available, and the labels can additionally be provided with security perforations. One and the same sealing label variant can be used with an abundance of packaging materials and numerous different surfaces. The transparent, glossy material does not cover the information on the package or interfere with the brand image.

Designed for reliable processing: labellers plus labels from HERMA

Besides sealing labels, HERMA also offers labelling machinery that can be integrated into your packaging facilities for perfectly coordinated production. Attaching tamper-evident labels requires a high degree of precision. The labels, which are usually very small, must be stuck to the side of the tuck-in flap in such a way that they protrude by about half their length up and down beyond the body of the folding carton. A folding rail then “irons” the two unattached parts of the label through 90 degrees, and foam rollers press the labels against the pack so that the tuck-in flap is permanently affixed to the carton. The machine is equipped with sensors for checking the placement of the labels and rejecting any defective ones. Labels can also be given special characteristics, such as luminescence, to facilitate the inspection process.
