Extremely strong tack with a clear view

• HERMA has optimized the 62Xpc adhesive for films with regard to flow behaviour and transparency.

• HERMAperfectCut (62Xpc) thereby achieves not only extremely strong tack, but also considerably increased clarity.

• HERMAperfectCut (62Xpc) is especially suited for high-quality film labels in growth segments such as cosmetics, personal hygiene, and cleaning products.

Rough or difficult-to-label surfaces are a challenge for product identification in production processes. It is crucial for the adhesive to ensure immediate tack despite the very high labelling speed, preventing the label from slipping out of place and its corners from protruding. HERMA’s optimized multi-layer adhesive 62Xpc, which will be presented at the Labelexpo 2017 in Brussels (hall 5, booth C14), is an ideal solution for these applications. After further development, HERMAperfectCut (62Xpc) penetrates surfaces much faster, thereby achieving extremely strong initial tack. “On top of that, we were able to increase the adhesive’s transparency. This results in a much better look, which plays a big role especially for high-quality film labels, e.g. in the demanding market of cosmetics, personal hygiene, and household cleaning products. Our optimized multi-layer adhesive 62Xpc offers users many possibilities in that field”, says Dr. Ulli Nägele, HERMA’s head of research and development.

Reduced die-cutting pressure

The HERMA adhesive 62Xpc not only provides fast flow behaviour – it also considerably reduces the clouding of label edges caused by prolonged contact with water. Moreover, the multi-layer adhesive offers excellent processing parameters – a major bonus for film applications in particular. The adhesive coating applied by the multi-layer process “breaks down” faster, for example, and thus facilitates the die-cutting operation during label production. Among other things, the die-cutting pressure can thus be decreased by 15 to 20 percent. This not only reduces wear, but also contributes to extending production machines’ service life. With this adhesive, furthermore, cohesion – the internal force that holds together the adhesive layer – has been significantly increased. Since practically no adhesive bleeding takes place as a result, the 62Xpc adhesive offers outstanding and reliable processability in the production environment, without exposing the user to any compromises as regards high initial tack and outstanding final adhesion. For labels to be able to play to their strengths during their entire period of use, the 62Xpc also provides excellent resistance to light, heat, and ageing. Additionally, the adhesive is completely migration-safe: it has the unrestricted approval for direct contact with foodstuffs.
