Manufacturers of food packaging are waking up to customer needs for packaging that is easy to use and has a long shelf value. Stand up pouches have emerged as the leader in flexible packaging and have millions of fans the world over. It is a groundbreaking packaging style and comes with a number of features.

Features and specialties of stand up pouches:

• Zipper locks: The very first specialty that has earned respect for standup bags is the zipper lock system. Many stand up pouches open with zippers. Of these, the single sliding zipper is the most popular one for granola. This gives customers greater control in the opening, sealing, and scooping the granola mix out of the pouches. Double track zippers are also available in some packs. Zippers make the pouches completely air tight. Granola is a highly perishable items but zipper locked pouches protect it from contamination and contact with moisture.
• Gas valves: Sometimes contents like coffee and tea emit gases inside the pack. This is different from their delicious aroma. If these gases continue to accumulate, the packaging would eventually bloat up and explode. Hence special valves are placed in stand up pouches to hold the aroma in while expelling the gas. These gases go to the outer chamber and are released once the pack is opened.
• Hang holes: Punched-in hang holes come with many pouches. This way your customers can hang the pouch when not in use. Both round and sombrero holes can be added according to the requirement. So whether you’re storing nuts, berries, pretzels, bagels, pastry, burgers, or granola mix, you can hang the pouch anywhere.
• Tear away notch: This is another useful feature. This easy-to-use locking mechanism makes opening the pouch quick and neat.
