This solution was identified as particularly suitable thanks to its ability to operate continuously, allowing the operator to insert one bag after another without interruptions while maintaining high productivity.
The machine is also designed to create strong and uniform seals even on thick bags with gussets, ensuring a reliable and professional closure.



Test performed
During the test, the bags supplied by the customer were tested, verifying the sealing quality and the continuity of the production process.
In the video, it is possible to observe the bags passing through the machine and the automatic, continuous welding process.
The tests showed a uniform seal across the entire width of the bag, with high mechanical strength of the sealing.
Result and conclusions
The FP FRM 1370 continuous band sealer proved to be perfectly suitable for the customer’s requirements.
The possibility of operating continuously made it possible to speed up the packaging process, while the quality of the weld achieved ensured a secure closure even on thick bags with gussets.
The proposed solution therefore represents an excellent choice for all companies that need to seal large industrial bags while maintaining high quality and production standards.
