Packaging redefined for moisture-sensitive and powdery goods
Around 15 years ago, RKW developed the RKW ProVent® plastic sack and set a completely new industry standard for the packaging of powdery and moisture-sensitive goods. The RKW Group was the world‘s first film manufacturer to develop a genuine alternative to conventional paper sacks. The innovation: An integrated venting system ensures that no dust, dirt or moisture can penetrate from the outside, and the only thing to escape is what should escape: air.
RKW has continuously developed this technological edge. The RKW ProVent® product family is today the top-selling solution for the packaging and marketing of powdery goods in the building materials, construction chemicals, chemical and food industries.

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.
