What is a valve bag?
Valve bags provide an efficient means to fill and securely close a flexible bag to prevent the contents from leaking or sifting out once it has been filled. A valve bag is totally sealed on all sides prior to filling except for an open sleeve located in a corner to allow introduction of material that is to be held within. The valve sleeve functions as a one-way or check valve to keep the contents from escaping after it is loaded.
They are filled with specialized, automatic filling machines that are classified simply enough as valve bag fillers. During the filling process, an empty valve bag is projected onto the filling tube or filling spout of a filler. The spout penetrates through the open sleeve into the interior. Product is then passed through the tube to the inside of the valve bag. Once completely filled, the product inside the bag pushes the one-way valve closed, preventing the product from leaking out. They are commonly used to contain and transport material such as dry powders and granular products, examples of which are cement, concrete, minerals, chemicals, seeds, grains and fertilizers. They can be constructed of a variety of materials including paper, plastic film and plastic woven mesh.
