Types and scope of stand up packaging bags

There are many types of stand up bags. At present, they are mainly divided into five types of stand up bags. The details are described below:
1. Ordinary stand-up pouch: The general-type stand-up pouch adopts four-side sealing and cannot be re-closed and re-opened. The ordinary stand-up pouch is generally used for the packaging of industrial products.
2. Nozzle stand-up pouch: The stand-up pouch with nozzle is more convenient for pouring out the contents of the package. At the same time, it is a nozzle device that can be closed and reopened. This kind of bag is a combination of stand-up bag and bottle mouth. This kind of stand up bag is generally used in liquids such as beverages, liquid toiletries, ketchup, and edible oil.
3. Stand-up pouch with zipper: Stand-up pouch with zipper can also be re-closed and re-opened. Due to the limited tightness of the zipper, this kind of bag is not suitable for packaging liquids and volatile substances. According to different edge banding methods, it can be divided into eight-side sealing and three-side sealing. Self-supporting bags with zippers are generally used to pack some solid products, such as candies, biscuits, jelly, rice, cat food and other products.
4. Special-shaped stand-up pouch: According to the packaging needs, the new stand-up pouch of various shapes, such as waist design, bottom modification design, portable design, etc., is changed on the basis of traditional bag type.
