RKW ProVent®

RKW ProVent®

RKW originally developed ProVent® as an efficient, sustainable, weatherproof and durable alternative to conventional paper packaging for powdery and moisture sensitive goods. The ProVent ® plastic sack significantly improves the filling, transporting, storing and distributing process of powdery and moisture sensitive goods whilst allowing deaeration through an integrated venting system that ensures no dust, dirt or moisture can penetrate from the outside, whilst only allowing air to escape from the inside.

What’s more, RKW ProVent® plastic sacks are much more environmentally friendly than paper sacks. The production of the RKW ProVent® pack consumes 14 % less energy than paper sacks. Just 20% of the typical amount of waste water and water pollution is produced, and because no composite materials are used, recycling is simple and inexpensive. In comparison to paper sacks, recycling a tonne of plastic takes up just 10 % of the otherwise required amount of energy.

With over 500 million sold, the RKW ProVent® family of products is today the top-selling solution for the packing and marketing of powdery goods in the building materials, construction, chemical and food industries.
