Self-Supporting Bag with Zipper, Nuts, Dried Fruit, Tea, Coffee Beans, Cat Food, Cat Litter

(The latest activity: buy packaging bags and send them to packaging machines, please consult for details!)

The design of the stand-up bag with zipper can make the bag can be closed and opened repeatedly, and the storage is more convenient.Since the zipper form is not closed and the sealing strength is limited, this form is not suitable for encapsulating liquids and volatile substances.

According to the different edge sealing methods, it is divided into four edge sealing and three edge sealing. Four edge sealing means that the product packaging has a layer of ordinary edge sealing in addition to the zipper seal when it leaves the factory. The zipper is then used to achieve repeated sealing and opening, which solves the disadvantage that the zipper edge sealing strength is small and is not conducive to transportation. The three-sealed edge is directly sealed with a zipper edge, which is generally used to hold lightweight products. Self-supporting pouches with zippers are generally used to package some light solids, such as candy, biscuits, jelly, etc., but four-sided self-supporting pouches can also be used to package heavier products such as rice and cat litter.

For stand-up pouches with zippers, our packaging machines can be equipped with a zipper-opening accessory for fully automated packaging.
