2. Stand-up bag with suction nozzle:

The stand-up bag with a suction nozzle is more convenient to dump or absorb contents and can be re-closed and re-opened, which can be considered as the combination of a stand-up bag and an ordinary bottle mouth. This kind of self-standing bag is generally used for daily necessities packaging, for holding drinks, shower gel, shampoo, tomato sauce, edible oil, jelly, and other liquid, colloidal, semi-solid products, etc.

3. Zippered Standby Bag:

Zippered stand-up bags can also be re-closed and re-opened, because the zipper form is not closed and the sealing strength is limited, so 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 there is a layer of ordinary edge sealing in addition to the zipper sealing when the product packaging leaves the factory. When using, it is necessary to tear the ordinary edge first, and then use the zipper to realize repeated sealing. The three edge sealing is direct with zipper edge sealing as sealing, generally used for dressing light products.

4. Mouth-like self-supporting bag:

The fake-mouth stand-up bag combines the convenience of a stand-up bag with a suction nozzle with the cheapness of a regular stand-up bag. The function of the suction nozzle is realized through the shape of the bag body itself. But the imitation mouth type stand-up bag can not be repeatedly sealed, therefore, generally used in drinks, jelly, and other disposable liquid, colloid, semi-solid product packaging.
