Superior Sealing, Maximum Protection
A Pinch Bottom Open Mouth ("PBOM") multi-wall paper bag is a common industrial packaging style designed to package a wide variety of dry flowable products. A PBOM bag offers the best sealing capabilities in the multi-wall paper bag family. Open Mouth bags are packed on equipment that deposits material into the bag via hopper or vertical filling spout. Once the bag is filled, a pinch sealer closes the bag by activating pre-applied glue on the bag’s opening with hot air, folding the open end over to complete the closure, and pinching the fold closed until the glue cures. The result is a completely sealed package. Pinch-style bags can be used on manual or fully automated equipment.

A Webb Pinch Open Mouth (SSWPT) bag is a combination of 2 common multi-wall bag styles. A Webb Pinch bag has an SOS (Self Opening Satchel) rectangular base and a PBOM top (stepped top with pre-applied hot melt). Webb bags can be self-standing and offer better palletizing functionality that standard PBOM bags.
PBOMA PBOM bag is formed by folding and hermetically sealing the top and bottom openings of the bag. A filled PBOM bag is rectangular on the bottom and tapered on top. PBOM and Webb bags offer a variety of barrier options for optimal product protection.
