The stand up pouch was a revolution in packaging, but with no liquid-tight closure it was only suitable for dry or nearly dry contents or single use liquid products.
That barrier is gone with the invention of the spout bag closures, finally allowing soft, efficient packaging for customers with liquid products.
Available in a range of sizes, closures can be as simple as a threaded cap or as complex as a sprayer. Spout bags are ideal for oxygen or air sensitive products, as the soft packaging collapses and is emptied, keeping the air space to a minimum.
