Functional, flexible, progressive
Around 10 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.
What’s more, RKW ProVent® are much more environmentally friendly than paper sacks. The production of the RKW ProVent® 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 400 million samples sold, the RKW ProVent® family of products is today the top-selling solution for the packaging and marketing of powdery goods in the building materials, construction chemicals, chemical and food industries.
