Complex Venting Systems For FFS Bags – The Solution For High-Quality Building MaterialsJanuary 27, 2021
For high-quality building materials, the demand for FFS film sacks as packaging is increasing. These benefit from high moisture protection and a long shelf life. However, for efficient filling of these often very dusty materials, good ventilation of the sack is required at the same time. How can these conflicting requirements of good venting and high sealing at the same time be combined? Complex venting systems, so-called labyrinth systems, are the answer. The POLYTEX as the universally applicable tube former from W&H is able to apply these complex venting systems.
