Also known as “quadro” bags, they allow products to hold its shape better and stand upright securely. Their seal design offers safeguards against leaks, punctures, and contamination.
Quad Seal Bag
With four reinforced panels, this structure is great for bulk packaging offering both added strength and a compact, space efficient form.
A quad pouch is a versatile packaging solution featuring four-corner seals — one at each corner — combined with top and bottom seals. This structure creates a stable, box-like shape that helps products stand upright and hold their shape better, even with heavier or bulkier contents.
Key Benefits of Quad Seal Pouch

The four-corner seal distributes pressure evenly across the bag, helping the filled bag maintain form during storage, handling, and transport.
Space Efficiency

Extended Branding
Pouch structure offers the extra space you need for product information, promotional graphics, and regulatory details.
Custom Features
Easy integration of functional elements like resealable closures, spouts, and degassing valves for coffee packaging bags.
