Proven quality with high print quality and highest functional safety
Safe outdoor storage in all seasons
Moisture protection up to 40 times greater than paper sacks
Impact and tear resistant packaging for safe transportation and handling
Significantly extended product storage life
Proven over more than 10 years, this popular classic features the well-known venting system. The RKW ProVent® Classic supports a high print quality and—like the entire product family—offers a high level of functional safety. All sacks are impact and tear proof and remain robust even when subjected to higher loads.
Thanks to their high level of weather resistance, RKW ProVent® sacks can also be used to store your powdery products safely outdoors. This provides a cost-effective and easy method of extending storage capacities. Even bulk goods that are particularly sensitive to moisture, such as plaster or cement, are safe outside.
The intelligent venting system ensures that nothing can penetrate from outside: No dust, no dirt, no moisture—even after several hours of immersion in a water bath.
Enhanced water barrier for particularly hydrophilic goods
Additional longitudinal seam to protect particularly fine powder
Improved sealing seam for highly contaminated weld areas
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.
