Kraft Paper Sewn bottom open mouth bag

A Sewn Open Mouth (“SOM”) multi-wall paper bag is a common industrial packaging style designed to package a wide variety of dry flowable products. The SOM 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 can be equipped with an easy-open pull tape feature to quickly open the bag and discharge its contents.

SOM bags were one of the earliest multi-wall bag constructions available in the market. Today they remain a tough, economical, workhorse bag style for a broad range of applications. Bags can be packed on manual or fully automated equipment.
