Henkel presents hotmelt for pressure-sensitive labels

Pressure-sensitive labels have to meet high standards of quality, their machinability and dispensing behavior being just as important as the visual impact. For premium consumer goods in the personal and home care sector in particular, the label has to sit tight to the very last drop – even when exposed to high mechanical stressing. Henkel has produced an adhesive system which it claims is the solution.

Having engineered a portfolio of pressure-sensitive adhesives for applications with a ‘no label’ look, Henkel has now introduced Technomelt 8707 hotmelt, which is claimed to hold the label firmly in place even in the face of repeated high stressing.

In packaging development, transparent film labels with a ‘no label’ look are becoming increasingly important. They not only have to be crystal clear, but also have to withstand extreme stressing throughout the branded product’s useful life - particularly on squeezable containers such as those used for shower gel, shampoo, dishwashing detergent and styling products, the made-to-measure brand label has to sit tight to the last drop. New Technomelt PS 8707 has ‘all the credentials – even for the most difficult surfaces like freshly blown PE and PP bottles’, said the company in a statement.

The statement continued: ‘Technomelt PS 8707 also sets high standards in terms of processing. The hotmelt allows easy die cutting, doesn’t bleed at the edges even at high ambient temperatures, and dispenses well even on difficult surfaces and at high speeds. Moreover, for a limited period Technomelt PS 8707 can be removed without a trace from conventional substrates – PP and PE, for example. Technomelt PS 8707’s high dimensional stability even permits the labeling of hot-filled oil canisters. This is because the adhesive is capable of expanding with the container and shrinking again upon cooling without leaving residues.’
