Open Mouth Bag
Open mouth bags provide a versatile means to package virtually any type of product. An open mouth bag has one open end through
which product is filled through a large throated spout. Open mouth bags are filled with specialized filling machines that
are classified simply enough as open mouth bag fillers. Filling and sealing open mouth bags is a two step process. During
the filling process, the open end of an empty open mouth bag is placed underneath the filling spout of an open mouth bag
filler. The spout slips inside the bag’s open end and is securely clamped to prevent product spillage during the filling
process.
Valve Bags
Valve bags provide an efficient means to fill and securely close a flexible bag to prevent the contents of the bag from
leaking or sifting out of the bag once the bag has been filled. A valve bag is totally sealed on all sides prior to bag
filling except for an open sleeve located in a corner of the bag to allow introduction of material that is to be held within
the bag. The valve sleeve of the bag functions as a one-way or check valve to keep the contents from escaping after it is
loaded.
