Technology partner for hemp pre-roll production

With its portfolio of machines and services for processing the hemp plant, the Hauni Group offers customers automated production solutions that cover the entire process from hemp plant to cylindrical pre-roll products. We help our customers to grow alongside the upcoming market for hemp products (premium CBD, THC and pre-rolls) – whether they are a small start-up or a large corporation. We offer scalable solutions tailored to their needs. The Hauni Group does this by drawing on its expertise as the world's leading technology producer of tobacco processing plants and machinery.

Our new machines for the preroll making take into account the specialties of the industry and material. Combined with our portfolio for the tobacco industry, we are able to meet your individual requirements. The cylindrical preroll (cigarette style) offers major advantages thanks to much lower production costs and more possible individualizations in comparison to the conical shaped prerolls. We are looking forward to getting you started.
