The valve bag is designed for the automated high-speed filling through the valve. It has an external or internal valve to match the special filling machine. The option of material can be plastic, paper or aluminum foil.
The valve bag has the characteristics of improving packing efficiency, convenient transportation, strong firmness, and low breakage rate. Compared with the ordinary bag, it has a series of advantages in the application for chemical particles and powder, as well as agricultural products such as starch and fertilizer.
Here at SHU Packaging, we are a professional packaging bag manufacturer that offers different material valve bags with many options. For more details of what is a valve bag and differences between different material, please read our Why Your Business Needs Valve Bags?
Valve port and tension design ensure that the valve bags will reduce the loss of the packaged material and reduce dust during the process of filling, transportation, and storage.
The upper and bottom of the valve bags are all square which makes it can stack higher and saves more storage space.

Depending on the required level of sift proofness and the cleanness of working environment, there are 3 different types of closure for valve bags.
Self-sealing valve bags are held closed by the force of the content inside the bag, but self-sealing bags do not provide food-grade sealing.
A traditional way to seal the bag by generating external heat by heat sealers.
The most advanced sealing process for valve bags is ultrasonic sealing, which provides a hermetic seal that prevents the flow of air and moisture into a packaging bag. This type of valve bag is only used in very specific industries such as dry food industry which need cleanliness and preventing contaminants from entering packaging during filling.
