Eight-side Seal Mylar Coffee Pouches With Pre-zipper Pre-zippered or "pocket-zipper" bags offer convenience for packagers and end-users alike. For the packager, products can be filled past the zipper without becoming trapped in the zipper tracks. This is because the zipper is protected and positioned on one side of the bag, whereas traditional zippers are located on each side of the bag, which means contents can become trapped in the zipper during the fill process. Pocket zipper bags are also convenient for consumers because they are "tamper-evident" and assure the customer that contents are safe and untampered with. Once the pull-tab has been torn away, consumers are able to access the standard press to close zipper hidden beneath. This offers a satisfying opening experience, and the convenience of being reclosable for repeated access.
