Herma extends opaque product range

The advantages of HERMAperfectOpaque adhesives are now also available for film labels

Herma has extended its opaque product range, with the new polypropylene film, PP white extra topcoat (grade 880), now available combined with HERMAperfectOpaque adhesives as a standard product.

Herma PP white extra topcoat (grade 880) allows users to produce visually appealing, glossy, non-transparent labels. For recycling reasons, Herma said these labels are preferably used on PP surfaces. A special surface treatment also means the film ensures optimal printing quality with standard printing methods, such as UV flexo printing and UV letterpress printing.

Ralf Drache, sales director for Germany and head of marketing at Herma Self-adhesive Materials, commented: ‘The new opaque adhesives’ special feature is that they can be combined with virtually all standard label materials – this film proves it once again. Label printers and users can therefore take advantage of a greater range. They no longer need to settle for such a limited range of colored label materials.’

Herma’s multi-layer technology removes the use of carbon particles that are usually used to color conventional adhesives. This means they usually do not receive approval for food applications. The HERMAperfectOpaque range uses a new pigment, and the adhesives have received approval for direct contact with foodstuffs.

The new PP film is combined with 62Gpo. First introduced at Labelexpo Europe 2017, this adhesive can cover critical applications requiring, for instance, extremely high tack or featuring damp and/or cool substrate surfaces. The opacity achieved by means of the multi-layer technology matches that of previous methods.

The opaque standard product range also includes white adhesive label papers, HERMAextracoat (grade 242) and HERMAlaser sheet (grade 135), as well as the white thermal paper HERMAtherm top M (grade 912).

Drache added: ‘If requested by customers, we will of course also produce different label materials featuring the opaque adhesives.’

Thanks to the special pigment qualities, Herma said it is currently the only manufacturer capable of producing opaque thermal Eco adhesive materials. Unlike carbon, which was used until now, the new color pigments will not affect the thermal reaction.
