Valve sacks from TENAX
High quality industrial packaging made in Germany

Paper valve sacks are among the most popular industrial packaging – for good reason: in terms of filling performance, paper valve sacks impress with maximum filling speed, clearly outperforming sacks made of plastic. The reason for this lies in the quality of the kraft paper processed. TENAX uses only high-elongation Semi Clupak paper made from long-fiber softwoods, which ensures first-class TEA values and maximum air permeability.

Especially when packaging fine powder products – such as cement or flour – TENAX customers benefit from our high-quality sack designs, which guarantee absolute impermeability combined with high venting performance. In addition, TENAX paper valve sacks are convincing in terms of sustainability: they are made from renewable raw materials sourced from responsibly managed forests and can also be recycled up to eight times until they are disposed of in a biodegradable way.
