Applications
Valve bags, also known as bottom-sealed bags, feature a valve opening at the top corner. The filling nozzle is inserted into the valve during packaging, and the process remains sealed. These bags are commonly used for packaging powdered materials, preventing spills and splashes. Self-sealing can be achieved with just a bottomer machine, eliminating the need for additional sealing processes.
Key benefits of valve bags:
- Accurate weight control during packaging
- Aesthetically pleasing
- Easy to stack
- No need for additional sealing, saving labor and increasing production efficiency
