ValvoSeal: Ultrasonic welding for maximum safety during bagging

safe – robust – reliable

The GREIF-VELOX ValvoSeal offers a patented ultrasonic welding process that ensures the highest level of safety and strength when sealing valve bags.

This technology is ideal for industries that rely on maximum product safety and a clean, tight seal when bagging various materials.

Secure Sealing
ValvoSeal uses patented "Waffle Welding" technology to seal valve bags securely and tightly. This method is on average 60% safer than other sealing methods and effectively prevents product leakage and contamination.

Cost savings
The robust seal minimizes product loss and increases the shelf life of the bags, resulting in significant cost savings in the long term.

Application flexibility
ValvoSeal is suitable for valve bags made of various materials such as paper, PE and PP and is used in various industries including chemical, petrochemical and food.

ValvoSeal: The innovative solution for securely sealed bags

Bags: tight and secure

Extremely high loss rates due to unsafe welding

ValvoSeal minimizes product leakage and contamination through extremely safe and robust ultrasonic welding, which significantly improves product quality and customer satisfaction.

Increased costs due to product losses and complaints

With ValvoSeal, the bags are securely sealed, significantly reducing product losses and complaints, resulting in a rapid return on investment.

Great time expenditure due to slow manual welding

Automatic ultrasonic welding by ValvoSeal increases production efficiency and reduces the need for manual intervention.

Risk to product safety due to unreliable closures

ValvoSeal ensures maximum product safety through its patented sealing technology, which guarantees reliable sealing and increases the durability of the bags.

As part of a closed production system, our filling systems go far beyond the pure filling function: They form an integral part of an overall system that fits seamlessly into and complements existing production lines.

Our full-line systems are able to meet complex requirements from container provision to filling to post-processing and storage, which makes us a holistic system provider in production technology. The focus is on individual adaptation to ensure optimal integration into the respective operational processes.
