The most defining feature of a paper valve bag is its "valve," a small opening in one corner of the bag. This allows it to be filled using special equipment. Unlike traditional open-mouth bags that need to be sewn or sealed shut after filling, the pressure from the product inside the bag causes the valve to automatically close and self-seal. This makes the filling process much faster and more efficient, reducing labor costs and spills.
Advantages
High-Speed Filling: They are ideal for automated and high-speed production lines because of their easy, spout-based filling process.
Self-Sealing: The valve design eliminates the need for extra sealing steps, making the process cleaner and more streamlined.
Secure and Tidy: Once filled, the bags form a stable, square shape, which is great for stacking on pallets. This makes storage and transportation more secure and efficient.
Customizable: Paper valve bags can be made with multiple layers of kraft paper, and manufacturers can add features like moisture-resistant coatings or plastic liners to protect the contents. They can also be customized with various printing options for branding.
