Quad Seal pouches have four tucked in sides. When the four corners are sealed, we call this a Quad Seal OR Quadro Seal pouch. These seals give the packaging greater stability and a sleeker look. The strong construction makes both types of packaging suitable for packaging liquid and solid products. Filled with bulk products, these types of packaging remain upright. As there is no back seal, all four panels maximise printing area & allowing front & back panel to be printed in full. The bag is heat sealed at the corners, with the seal only visible in the corners. This style is known for being robust, versatile and easy to handle in filling, handling and on the shelves.
