Seal as proof for authenticity, according to EU Directive 2011/32/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. 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.

The benefits for you:

  • Sealing labels that efficiently comply with tamper-evident requirements
  • Extremely strong adhesion and excellent flexibility – for labelling curved surfaces with small radii and labelling around corners
  • Suitability for all common tuck-in flaps, no need to change the carton design
  • Highly resistant adhesives for reliability
  • Increased protection against tampering (for example, by means of security perforations)
  • Proof of authenticity and provision of security (tamper-evident)
  • Suitability for many different packaging materials and surfaces
  • An integrated solution comprising tamper-evident labels plus a labelling machine with a modular design – perfectly coordinated high-speed production

In addition to special tamper-evident labels HERMA offers sealing solutions for a wide range of requirements, for example packaging of foodstuffs:

  • Resealing of packaging
    HERMA sealing labels allow easy resealing of packages that have been opened. No damage is done to the packaging. The product is kept fresh and is ideally protected – your customers will appreciate this because they will not need any other kind of seal. Another advantage is that the labels can be resealed even when the package surface is uneven. Sealing labels are manufactured from film, sometimes with partial adhesion. Special stamping and gripping tabs ensure easy use. Whether you need printed or unprinted labels, HERMA can produce them on rolls to your specifications. They can be applied to film, cardboard, paper or plastic.
  • Tamper resistance and proof of authenticity
    There are many names for labels of this kind: security labels, anti-tamper labels, tamper-evident labels, anti-counterfeiting labels. What they all have in common is a focus on tamper protection and product authentication. HERMA sealing labels show users that products have not been opened or tampered with. They can be applied to all kinds of surfaces: film, cardboard, paper, plastic or metal. HERMA offers a wide range of high-security solutions. Our specialists will produce sealing labels for you made of special composites (tamper-evident, void) and with security perforations. Also for extreme conditions. With extremely strong adhesives. On rolls, printed or unprinted.
  • Versatility
    Our sealing labels can be applied to packaging made of film, paper, plastic, metal or glass, ensuring secure closure even when used on corners on uneven surfaces. They can even hold cardboard boxes together. Find out for yourself and benefit from the expertise of HERMA’s application engineers..
  • Other applications
    HERMA sealing labels can also be used as promotional labels, for example to convey advertising messages. Get the most out of our sealing labels by adding product information, best-before dates, batch numbers or instructions on use.
