Herma adhesive approved for direct food contact

The 42Lpp adhesive can be peeled off many surfaces absolutely cleanly, without leaving either any residue or an outline. This property is retained even after prolonged exposure to light and heat. Ghosting does also not occur when using 42Lpp, Herma said.

The adhesive can be applied to thermal paper grades as label materials, and with immediate effect, 42Lpp can be supplied as standard with labelstock made of film. The available options are a white PP film (grade 880), a transparent PP film (grade 885) and a white PE film (grade 851).

ISEGA approval means 42Lpp is suitable for use with dry and moist foodstuffs, and fatty foods.

‘An adhesive that can be removed without leaving any residue on a wide variety of surfaces while offering such extensive food compatibility has thus far proven elusive in practice,’ said Herma managing director Dr Thomas Baumgärtner.

‘Thanks to our multi-layer technology, we can offer both benefits at once with an acrylate-based dispersion adhesive.’

Baumgärtner added: ‘Because of the special second layer, moreover, we can entirely forgo the plasticizers, which often attack the substrate and migrate through the labelstock.’
