Sewn Open Mouth Bag(SOM)

Sewn Open Mouth bag is an open mouth bag that is closed using sewing thread. Open mouth bags are packed on equipment that deposits material into the bag via hopper or vertical filling spout. The bottom of the bag is pre-closed by the bag manufacturer. Once the bag is filled, the flush cut open end of the bag is sewn closed by the user.

SOM bags are closed using sewing thread. SOM bags are a good choice for dry products that do not require barrier protection and can be made to be opened using only a single cord for easy access.
