Tamperproof along the supply chain

Herma has introduced a tamperproof self-adhesive material HermAvoid checkerboard (type 935) especially for challenging applications on rougher (transport) cardboard. This is because demand for security labels is growing robustly: the market is expected to grow by around 7% annually worldwide over the next few years. While sales in 2023 were just under 32 billion dollars, Grand View Research, one of the leading international market research specialists, estimates that this figure will exceed 50 billion dollars by 2030.

An important driver of this development is the ongoing e-commerce boom. This is because the protection of transport packaging containing high value products shipped via is also becoming increasingly important, as these products often pass through several handling points. The new HermAvoid checkerboard (type 935) is a silver metallised PET self-adhesive material with a concealed tamperproof pattern on the reverse side. If a label made from this material is removed from the product, the characteristic checkerboard pattern remains visible on the surface. Attempts at tampering are thus immediately recognisable, and reuse of the label is impossible. For this reason, HermAvoid checkerboard (935) is equipped with the 63B adhesive, which has already proven itself in other areas and impresses with its particularly aggressive adhesive properties. It is ideal for critical substrates such as rough cardboard.

In addition, the adhesive is characterised by very good water resistance and is even suitable for cool and damp surfaces. The new self-adhesive material thus forms an ideal basis for tamper evident and void labels, especially for cardboard transport packaging, but also for many other surfaces.

Its properties make HermAvoid checkerboard equally interesting for label producers and label users. 'It offers label printers the opportunity to participate in an extremely attractive, steadily growing market. And label users get an efficient and cost effective solution for protecting products, brands and property along supply chains,‘ emphasised Hendrik Kehl, product manager. At the same time, the new self-adhesive material opens up many design possibilities. This is because it can be processed using conventional printing methods such as UV flexographic printing, letterpress printing or screen printing. On request, the chequerboard pattern can be adapted to brand or application specific requirements, for example with customised lettering or a logo. Herma offers this variant as a custom made product.
