Success has tradition

Continuity and customer satisfaction – this is what we at Lenzhard have focused on since the company was founded in 1876. Founded as Kartonagenfabrik J. Langenbach AG in Lenzburg, we initially manufactured cardboard articles. From 1932, we specialised more and more on the production of mailing cores. In the mid-1960s, we finally established the paper core production as an independent division and in 1989, we were taken over by the Kunert Group. This close cooperation with the paper core specialist Paul & Co of the Kunert Group, also enables us to offer the entire range of paper cores and edge protectors from Paul & Co in addition to our paper cores. Together we successfully supply the markets in Switzerland and Italy. We are happy to advise you, naturally also if you have individual requests.

Our stated aim has been and always will be: A long-term, trusting relationship with you, our customers. Together with you we have gathered experience over the years. We do not see ourselves as a mere manufacturing company. Instead, we are a customer-oriented service company where you, our customers, are the priority.
