Eticol borax- and zinc-free casein-based labelling adhesives

Henkel has launched its Eticol borax- and zinc-free casein-based labelling adhesives, which give good bonding power and may contribute to improved sustainability at bottling plants.

Eticol casein-based adhesives use water-based adhesives. The range gives good bonding behaviour on moist and cold bottle surfaces. Labels also adhere strongly to the bottle if condensation forms on the glass.

The product range is available in a number of variants, such as with high wet tack and good ice-water resistance. The adhesives can be used in conjunction with labelling machines without difficulty, even at maximum speeds, Henkel says.

The adhesive technology is based on natural polymers that are obtained from the raw material casein. Until recently, some Eticol adhesives still contained borax or zinc in quantities below the strict statutory limit values. The recently released Eticol products do not contain any borax or zinc. This can have a positive impact on factors such as wastewater produced by bottlers, as well as the minimum shelf life and quality of the adhesives.
