Classification of stand-up bags
Stand-up bags are basically divided into the following five types:
1. Ordinary stand up bag:
And the general form of stand-up pouch, which adopts the form of four-sealed edges and cannot be re-closed and repeatedly opened. This kind of stand-up pouch is generally used in the industrial supplies industry.
2. Stand-up pouch with suction nozzle:

This kind of stand-up pouch is generally used in the packaging of daily necessities, for beverages, shower gels, shampoos, ketchup, edible oils, jelly and other liquid, colloidal and semi-solid products, such as the famous CiCi.
3. Stand up pouch with zipper:
Self-supporting pouches with zippers can also be re-closed and re-opened. 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 used to achieve repeated sealing and opening, which solves the shortcoming of the small edge sealing strength of the zipper, which 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.

Therefore, it is generally used in the packaging of single-use liquid, colloidal and semi-solid products such as beverages and jelly.
5. Special-shaped stand-up bag:
That is, according to the needs of packaging, new stand-up bags of various shapes are produced by changing on the basis of traditional bag types, such as waist design, bottom deformation design, handle design, etc. It is the main direction of the value-added development of self-supporting bags.
With the progress of society, the improvement of people's aesthetic level and the intensification of competition in various industries, the design and printing of stand-up bags have become more and more colorful, and their forms are more and more.
