With the HERMA62L luminophore adhesive, 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.
Because closure labels and others on pharmaceutical packaging are often transparent for optical reasons, their seamless and reliable presence monitoring using optical sensors is a challenge. Past labels were equipped with luminophores that become visible and detectable as soon as they are exposed to UV light. Generally, this was achieved with a special varnish that was applied to the labels. With the new HERMA 62L adhesive, the luminophores are already integrated during the coating of the adhesive bond.
