Treating the folded base as proof of barrier or leak resistance
Packaging format
Fold-and-Glued Bottom Bags
A fold-and-glued bottom bag uses a folded base to give a gusseted bag its finished shape. It is a useful format to consider for pet food and other dry products when bag size, filling, and presentation need to work together.
PROJECT FOCUSA different bottom construction for a larger bag.
Compare a folded-base bag with other specialty formats, then confirm the actual construction with samples.
What the specification must resolve
What to confirm before production.
The folded and glued base is different from a heat-sealed flat-bottom pouch. We review the bag with the fill weight, filling equipment, and shipping requirements. A terminated gusset can keep extra folded material out of the top sealing area. Press-to-close and hook-to-hook closures can also be considered for the application.
Key considerations
- Fill weight and finished base dimensions
- Gusset design and top-sealing area
- Closure and opening preference
- Bottom construction and handling performance
Common applications
- Dry pet food
- Pet treats
- Bulk dry foods
- Larger retail bags

A common question
Is this the same as a flat-bottom pouch?
No. Both can offer a defined base, but their construction differs. A fold-and-glued bottom bag has a folded, glued base. We can compare samples to help you choose the style that fits the product and packing process.
