Satchel Bottom Open Mouth

The satchel bottom open mouth bag is a merger of 2 distinct bag styles (Block Bottom Bag & Pinch Bottom Open Mouth). This unique bag type offers a square satchel style bottom and sealable open mouth top. Satchel bottom open mouth bags are closed/sealed by Pinch Bag Closers using a pre-applied hot-melt to create sift proof closures. Satchel bottom open mouth bags palletize and transport better than standard PBOM bags due to their square bottom.
