A quad pouch is a flexible 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.
With four reinforced panels, the structure of quad seal bags is great for bulk packaging offering both added strength and a compact, space efficient form. 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.
The four-corner seal distributes pressure evenly across the bag, helping the filled bag maintain form during storage, handling, and transport.
Uses less width for the same volume of product, maximising shelf density, a major advantage for brands with limited shelf space in retail.
Pouch structure offers the extra space you need for product information, promotional graphics, and regulatory details.
Easy integration of functional elements like resealable closures, spouts, and degassing valves for coffee packaging bags.
Quad packs are an alternative solution offering superior structure and presentation over standard gusset bags or rigid packaging. They outperform by providing more structural support for different products and pack weights. This is making them ideal for heavier contents and a perfect solution designed for food packaging industry.
The rectangular footprint of quad seal pouches provide the extra space needed in markets with limited shelf space.
