Lock in the freshness— resealable zipper bags that change the way you sell your products. Looking for high-quality, zipper bags? Tripod Thai Packaging offers stand up pouches that are the packaging choice for brands looking to transition out of traditional rigid packaging such as bottles, jars, and tins. Zipper Bags If you’ve spent any time using resealable bags at home, you know what it feels like to have a bag’s zipper close firmly and securely beneath your fingers. That feeling is your reassurance that whatever’s inside that bag will remain fresh for as long as possible. If you want to offer that reassurance to your own customers, you should give serious thought to shipping and selling your perishable products in bags that include these handy zippers. Here at Tripod Thai Packaging , we can provide you with zipper bags that also include numerous other features to help keep contents fresh. Anatomy of a Resealable Zipper A typical resealable zipper bag contains two zipper strips on opposing sides of the bag’s interior, aligned so that they mesh together near the top of the bag. J-shaped grooves on one strip interlock with pointed hooks on the other strip when the two strips are pressed together, forming an airtight seal that can be opened and closed at will. Just above the zipper strip, you’ll likely see little notches at the top of the sealed bag. These notches allow you to tear away the topmost bag material without damaging the zipper assembly or the body of the bag. Resealable zippers represent surprisingly old technology, with the earliest patent dating back to 1950. Over the decades that followed, a lot of science has gone into perfecting this technology, making today’s zipper bags more reliable and easier to use than ever. Many consumers have come to expect or prefer some form of resealable zipper on the products they purchase. If you want to compete with the sheer convenience and practicality offered by major brands that use resealable zipper bags, you’ll want to make sure you package your own products in this manner — especially if you sell highly perishable goods such as coffee, tea, or spices.
