This package features a flat-bottom design that allows it to stand upright even when the contents decrease, preventing it from tipping over. Its square shape minimizes dead space in cartons, and its compact design—achieved even at the same capacity—improves transportation efficiency. In addition, the smaller size enhances shelf display efficiency at retail stores, contributing to cost reduction. With ample printable areas on the front, back, side gussets, and bottom, it offers excellent design flexibility and strong visual appeal to consumers.

Tough Zip features the highest interlocking strength from the inside among zipper closures. Even if air is trapped inside the bag and an adult man stands on it after sealing, the zipper will not open. This eliminates concerns about the zipper opening during transportation of powder products and the contents spilling or dispersing when the bag is opened.

In addition to powder products, this high internal sealing strength zipper can be used for a wide range of applications.

Tear Rite is an easy and straight-opening system that allows the bag to be cut cleanly along the surface, made possible by our proprietary film. With just a notch, anyone can easily open the bag without using scissors. Because it enables a clean, straight cut, it is ideal for resealable bags such as zipper pouches that are used repeatedly.
