RKW ProVent® Flex
Flexible to the fullest: With a continuous print image and the flexible venting concept, sacks of different lengths can be produced in one production run. Efficiency that shows for every size.
One size fits most
Resistant to weather, shock, burst and tear
RKW ProVent® is characterized by its outstanding cost efficiency due, for example, to excellent machine runability and high filling speeds (up to 2,000 sacks/h). Another significant contribution to efficiency is the extension – and even the doubling – of storage life for bulk goods.
Thanks to further development of the technology, the RKW ProVent® can now also be produced with 5 film layers, resulting in even higher product performance - in particular, even higher impact resistance as well as up to 40 times better moisture barrier.
