The English name of the self-supporting bag originates from the French Thimonier company. In 1963, the CEO of the French Thimonier company, Mr. M. Louisdoyen, successfully applied for the patent of the Doypack self-supporting bag. Since then, doypack has become the official name of the self-supporting bag. In the 1990s, it was recognized in the American market and then popularized around the world.
Self-standing bag is a relatively novel form of packaging, which has advantages in many aspects such as improving product grade, strengthening the visual effect of shelves, portability, convenience of use, preservation and sealability. The self-standing bag is laminated by PET/foil/PET/PE structure, and can also have 2 layers, 3 layers and other specifications, according to the different products of the packaging, can increase the oxygen insulation protective layer according to the need to reduce the oxygen penetration rate and extend the shelf life of the product.

Self-standing bag packaging is mainly used in fruit juice drinks, sports drinks, bottled drinking water, absorbable jelly, condiments and other products, in addition to the food industry, some washing supplies, daily cosmetics, medical supplies and other products are gradually increasing.

Classification of self-supporting bags

Self-supporting bags are basically divided into the following five types:

  1. Ordinary self-supporting bag:
    And the general form of self-supporting bag, using four edge form, can not be re-closed and repeated opening, this self-supporting bag is generally used in the industrial supplies industry.
  2. Stand by bag with suction nozzle:
    The self-supporting bag with suction nozzle is more convenient to dump or absorb the contents, and can be re-closed and re-opened, which can be considered as a combination of self-supporting bag and ordinary bottle mouth. This kind of self-standing bag is generally used in daily necessities packaging, used to hold drinks, shower gel, shampoo, ketchup, cooking oil, jelly and other liquid, colloidal, semi-solid products, such as the famous Xizhlang CiCi and so on.
  3. Self-supporting 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, so this form is not suitable for packaging liquid and volatile substances. According to the different edge sealing method is divided into four edge and three edge two, four edge refers to the product packaging in the factory zipper seal there is a layer of ordinary edge sealing, the use of the first ordinary edge tear, and then the zipper to achieve repeated sealing, this method solves the zipper edge strength is not conducive to transportation shortcomings. The three sealing edges are directly sealed with zipper edges as a seal, which is generally used for holding lightweight products. The self-supporting bag with zipper is generally used to pack some light solids, such as candy, cookies, jelly, etc., but the four-sided self-supporting bag can also be used to pack rice, cat litter and other heavy products.
  4. Self-standing bag with imitation mouth:
    The self-standing bag combines the convenience of a self-standing bag with a suction nozzle with the low cost of an ordinary self-standing bag. That is, the function of the suction nozzle is realized through the shape of the bag itself. However, the self-standing bag can not be repeatedly sealed, so it is generally used in the packaging of disposable liquid, colloidal and semi-solid products such as beverages and jelly.
  5. Shaped Self-supporting bag:
    That is, according to the packaging needs, new self-supporting bags of various shapes generated by changes on the basis of traditional bag types, such as waist collection design, bottom deformation design, handle design and so on. It is the main direction of the development of self-supporting bags.
    With the improvement of social progress and people’s aesthetic level and the intensification of competition in various industries, the design and printing of self-supporting bags have become more and more colorful, and their forms of expression are more and more, and the development of special-shaped self-supporting bags has gradually replaced the status of traditional self-supporting bags.
