Herma has launched the 62L luminophore adhesive, for tamper-evident labels, making the presence monitoring of transparent labels becomes more reliable.
This results in clearly improved safety – for the product manufacturer as well as the product user. Security features, for example for protection against product piracy, are in great demand in many industries. They have even been legally prescribed for numerous pharmaceutical products across the EU since February 2019.
To make manipulation attempts visible, corresponding closure labels are often used, for example on folding boxes. They can be applied particularly economically without having to change existing packaging. In the past, labels were equipped with luminophores that become vsºisible and detectable as soon as they are exposed to UV light. With the new Herma 62L, the luminophores are already integrated during the coating of the adhesive bond. “The coating of the adhesive takes place with precision and uniformity that is clearly superior to typical commissioned varnish work,” says Herma’s head of development, Dr. Ulli Nägele.
The 62L adhesive used here is distinguished by additional advantages. Due to its high transparency and an extremely high whitening resistance, the 62L is, on the one hand, predestined for use in no-label-look labels, including for subsequent printing in multi-coloured UV-printing.
