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.

PBOM vs Webb Pinch
Both PBOM and Webb Pinch multi-wall paper bags are designed to provide strong closures and product protection. However, each has unique features that make them better suited for specific applications.
Webb Pinch Bags
Closure Method: Sewn closure at the top with a “webbed” reinforcement strip
Best For: Products that don’t require airtight sealing but need heavy-duty strength
Industries: Agriculture (seeds, grains, animal feed), minerals, construction products
Advantages:
- Reinforced top for durability during filling and transport
- Stronger sewn closure than a standard open-mouth bag
- More economical option compared to fully sealed PBOM
PBOM Bags
Closure Method: Heat-sealed closure using pre-applied adhesive and hot air
Best For: Dry, free-flowing products requiring sift-proof and tamper-resistant seals
Industries: Food ingredients (flour, sugar, starch), chemicals, pharmaceuticals, pet food
Advantages:
- Provides the most secure seal of all multi-wall paper bag styles
- Protects against contamination, moisture, and leakage
- Compatible with both manual and fully automated filling equipment
How do you choose?
Choose PBOM when you need the most secure, sift-proof seal (ideal for food and fine powders).
Choose Webb Pinch when product integrity is important but absolute sealing is not required (ideal for bulk feed, seed, or industrial materials).
