Why brands pick flat bottom
Flat bottom pouches stand upright on the shelf and pack more efficiently in the carton. We add a press-to-close or slider zipper, a laser tear notch and a die-cut hang hole so the pack works for both retail and club-store channels.

Frequently asked questions
What is the difference between a quad seal and an eight-side-seal pouch?
A quad seal bag has four vertical seals and one flat base. An eight-side-seal pouch adds four corner gussets for a more rigid, premium brick-like shape.
Can you make a 5 kg flat bottom pet food bag?
Yes. We produce flat bottom and quad seal bags from 1 kg to 5 kg with a reinforced base, zipper, tear notch and hang hole, using high-puncture film structures.
Do flat bottom pouches work on automatic filling lines?
Yes. We build flat bottom and quad seal pouches to VFFS and premade-pouch fillers, with welded corners and a flat base that keep the pack stable through filling and sealing.
What is the MOQ for a printed flat bottom pouch?
Rotogravure starts at 5,000 pieces. Digital printing from 500 pieces is ideal for a launch or seasonal line.
