Self standing bag refers to a flexible packaging bag with a horizontal support structure at the bottom, which can stand independently without any support and whether the bag is opened or not. Self standing bag is a relatively new packaging form, which has advantages in upgrading the product grade, enhancing the visual effect of the shelf, portability, convenient use, freshness and sealability. Today, we will talk about the classification of self-supporting bags.

 

 

Self standing bag classification:

 

1、 Ordinary self-supporting bag

 

The self-supporting bags and ordinary bags adopt the form of four edge sealing, which 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 for dumping or absorbing contents, and can be re closed and re opened, which 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, and is used to contain liquid, colloidal and semi-solid products such as beverages, shower gel, shampoo, tomato paste, edible oil, jelly, etc., such as the famous Xizhilang CiCi.

 

3、 Special shaped self-supporting bag

 

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

 

4、 Self standing bag with zipper

 

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

 

5、 Mouth like self-supporting bag

 

Mouth like self-supporting bag combines the convenience of self-supporting bag with suction nozzle with the cheapness of ordinary self-supporting bag. Namely, the function of the suction nozzle is realized through the shape of the bag itself. However, mouth like self-supporting bags cannot be sealed and opened repeatedly. Therefore, they are generally used for the packaging of liquid, colloid and semi-solid products for one-time use, such as beverages and jellies.
