Factory Supply Zipper Stand Up Pouch Bag - Good material Zipper Stand Up Pouch – Yudu

The zipper stand up pouch bag is also called the self-supporting bag.The self-supporting bag with zipper can also be re closed and re opened.  According to different edge banding methods, it is divided into four edge banding and three edge banding. Four edge banding means that there is a layer of ordinary edge banding in addition to the zipper sealing when the product package leaves the factory. When in use, the ordinary edge banding needs to be torn off first, and then the zipper is used to realize repeated sealing. This method solves the disadvantage that the zipper edge banding strength is small and is not conducive to transportation.
Its biggest feature is that it can stand, prolong the service life of built-in products, strengthen the visual effect of shelves, carry light, keep fresh and sealable.

Self standing bags are basically divided into the following five types:

1. Ordinary self-supporting bag:

And the general form of self-supporting bag, which adopts the form of four edge sealing and cannot be re closed and re opened. This self-supporting bag is generally used in the industrial supplies industry.

2. Self standing bag with suction nozzle:

The self-supporting bag with suction nozzle is more convenient to dump or absorb the contents, and can be closed and opened again. It can be considered as the combination of self-supporting bag and ordinary bottle mouth. This self-supporting bag is generally used in the packaging of daily necessities to hold liquid, colloidal and semi-solid products such as drinks, shower gel, shampoo, ketchup, edible oil and jelly.etc

3. Self standing bag with zipper:

The self-supporting bag with zipper can also be re closed and re opened. Because the zipper form is not closed and the sealing strength is limited, this form is not suitable for packaging liquids and volatile substances. According to different edge banding methods, it is divided into four edge banding and three edge banding. Four edge banding means that there is a layer of ordinary edge banding in addition to the zipper sealing when the product package leaves the factory. When in use, the ordinary edge banding needs to be torn off first, and then the zipper is used to realize repeated sealing. This method solves the disadvantage that the zipper edge banding strength is small and is not conducive to transportation. The three edge sealing directly uses the zipper edge sealing as the sealing, which is generally used to hold light products. The self-supporting bag with zipper is generally used to pack some light solids, such as candy, biscuits, jelly, etc., but the self-supporting bag with four edges can also be used to pack heavy products such as rice and cat litter.

4. Mouth like self-supporting bag:

The mouth like self-supporting bag combines the convenience of self-supporting bag with suction nozzle with the cheapness of ordinary self-supporting bag. That is, the function of the suction nozzle is realized through the shape of the bag body itself. However, mouth like self-supporting bags cannot be sealed and opened repeatedly. Therefore, they are generally used in the packaging of disposable liquid, colloidal and semi-solid products such as beverages and jelly.

5. Special shaped self-supporting bag:

That is, according to the packaging needs, new self-supporting bags of various shapes are produced by changing on the basis of traditional bag types, such as waist retraction design, bottom deformation design, handle design, etc. It is the main direction of value-added development of self-supporting bags.
