PBOM Packing for a Variety of Products

A Pinch Bottom Open Mouth (PBOM) multi-wall paper bag is a widely used packaging style for dry, free-flowing products. Known for providing the most secure seal among multi-wall paper bags, the PBOM design ensures product integrity from fill to final delivery. These bags are filled through a hopper or vertical spout, after which the top is sealed using pre-applied adhesive. Hot air activates the glue, the open end is folded over, and the fold is pressed closed until the adhesive sets. The result is a strong, sift-proof closure that fully protects the contents. PBOM bags are compatible with both manual and automated filling equipment, making them a versatile choice across industries.
