Closure labels are labels that seal a product. Their primary task is to guarantee secure first-opening protection for primary and secondary packaging. This protection has been a legal requirement for prescription pharmaceutical products in the EU since 2019.
Tamper evident labels
The so-called tamper evident labels are attached to the corner of the tuck-in flap of folding cartons, bottles, jars and cans, among other things. They can have integrated perforations to facilitate opening at the desired location. We also offer customised tamper evident labels for other types of containers.
Our tamper evident labels are equipped with strong adhesives that make it difficult to remove them without leaving any residue. This makes tampering immediately visible. To do this, we test the function of the labels in combination with the cardboard material and varnish used on your folding cartons. This helps you as a manufacturer to ensure safe first opening in accordance with European directives.
Example: Semi-clear paper tamper evident label
The environmentally friendly semi-clear Faller paper tamper evident label with tamper evident closure offers a first-opening guarantee for folding cartons in accordance with European Directive 2011/62/EU.
By attaching the label over the tuck-in flap of the folding carton, it prevents tampering with the product as the first opening is clearly visible.
The use of paper labels on folding cartons creates a sustainable mono-material solution for efficient recycling cycles.

Another variant is the so-called void label. If these are removed, the adhesive part of the label remains attached to the box, for example in the form of a chequerboard pattern or the word "void". This allows the user to recognise at a glance that the packaging has already been opened.
The outer material of the tamper evident labels usually consists of a transparent or silver polypropylene or polyester film. Closure and void labels can usually withstand temperatures between -30 and +80 degrees Celsius and are particularly resistant to light and ageing. This ensures a long shelf life and reliable function. On request, we can also equip the labels with additional security features such as die-cutting or microtext.
