TPE for membrane in packaging application for Goldwell

Goldwell exclusively supplies hair care products and hair colorations as well as service to hairdressers. A new product in their portfolio is a pump dispenser to apply the hair color evenly by means of pressure on the membranes. “Due to the chemical composition of the hair colorations as well as the high mechanical stress during the application, we needed a material for the membrane inside the application system, which is of such a high quality that it is able to withstand these high demands. At the same time, the materials have to meet European regulations concerning food contact, which also apply to our hair care products”, says Sebastian Kraus, Manager Packaging Development at the company Kao Germany, which is owner of the brand Goldwell. Moreover, the TPE compounds do not pose danger to the health of its users in the hairdressing trade: the TPE are free from PAHs, phthalates and allergens as well as RoHS- and REACH-compliant.

„We have already collaborated successfully with Kraiburg TPE in previous projects several times. That is why it did not take us long to choose the Thermolast K product series as a suitable TPE for our application system“, says Kraus. The pump dispensers are produced in a two-component injection moulding process which saves time and production costs compared to usual assembly steps. Together with Kao and the mould maker, Kraiburg TPE adjusted the production process to the injection moulding unit in order to achieve a good adhesion to the hard component PP.
