Stand-up pouch with zipper

        Stand-up pouches with zippers can also be re-closed and re-opened. Since the zipper is not closed with its limited closure strength, this form is not suitable for liquids and volatile substances. According to the different edge sealing methods, it is divided into two types: four-edge sealing and three-edge sealing. Four-edge sealing means that the product package has a layer of ordinary edge sealing besides the zipper seal when the packaging is finished. The ordinary edge sealing needs to be torn off before use. Then use the zipper to realize repeated sealing. This method solves the disadvantage of the zipper with small strength. The three-side seal is directly sealed with a zipper seal, which is generally used to hold lightweight products. Stand-up pouches with zipper are generally used to pack some light solids, such as candy, biscuits, jelly, etc., but stand-up bags with four sides can also be used to pack heavier products such as rice.
