RKW ProVent® Flex
Self-venting industrial bags

Maximum flexibility due to continuous
print image and flexible venting concept

  • Significantly extended storage life

One size fits most: The RKW ProVent®  Flex allows sacks of different lengths to be produced in one production run. At the same time, easy handling reduces operating time. As the entire RKW ProVent® product family, the RKW ProVent® Flex offers excellent machine runnability together with very high filling speeds.

Increase potential savings and boost sales volumes

When it comes to efficiency, the RKW ProVent® Flex leads the way in every respect. In addition to realizing potential cost savings, it provides an opportunity to boost sales volumes: Production peaks can be smoothed out by the significantly improved storage life—just one of the advantages of the entire RKW ProVent® product family.

For seasonal goods, in particular, this helps to avoid expensive peak production costs and increases sales volumes at the same time.
