Center Seal Pouch FAQ
A center seal pouch (also called a center seal bag or central seal pouch) features a single longitudinal seal running down the center of the back panel. This classic structure is cost-effective to produce, runs efficiently on automatic filling lines, and provides a clean front panel for maximum branding area. Compared to 3-side seal pouches, center sealed pouches offer better material utilization and are preferred for many snack, coffee, and dry food applications.
For digital printing, our MOQ starts at 500 pieces. For gravure (rotogravure) printing, the MOQ is typically 5,000 pieces per design due to cylinder setup costs. Contact us with your specific requirements — we can often accommodate smaller trial orders for new clients.
