Why choose quad seal bags?
A quad seal bag is a side-gusseted bag with all four vertical corners sealed. Those corner seals act like a frame, so the bag keeps a sharp, box-like shape, stands steadily when full and resists bulging.
With the front, back and both gussets available for printing, quad seal bags give you room for branding, storytelling and nutrition information. Add a one-way valve for fresh-roasted coffee, a pocket zipper for resealability and tear notches for easy opening.

What is a quad seal bag?
A side-gusseted bag with all four vertical corners sealed. The corner seals add strength and help the bag hold a crisp, box-like shape.
Quad seal or flat-bottom bag?
Both stand well. Flat-bottom bags have a folded box base and five printable panels; quad seal bags have four sealed corners that add rigidity and suit heavier fills. We can sample both so you can compare.
Can quad seal bags have valves and zippers?
Yes. One-way degassing valves, pocket zippers and tear notches can all be added.
What products suit quad seal bags?
Coffee, pet food and treats, rice and grains, snacks, and other heavier or bulk products.
