An introduction about self standing bags, hoping to be helpful for you in selecting product packaging.
Doypack refers to a soft packaging bag with a horizontal support structure at the bottom, which does not rely on any support and can stand on its own regardless of whether the bag is opened or not.
Doypack
The emergence of the English name for stand up pouch originated from the French company Thimonier. In 1963, Mr. M. Louis Doyen, who was then the CEO of the French company Thimonier, successfully applied for the Doypack stand up pouch patent. Since then, Doypack has become the official name for stand up pouch and has been used to this day. By the 1990s, it was widely recognized in the US market and subsequently popularized worldwide.
Stand up pouch are a relatively novel packaging form that has advantages in improving product grade, enhancing shelf visual effects, portability, convenient use, preservation, and sealability. The stand up pouch is made of PET/MPET/PE structure lamination, and can also have 2 or 3 layers of other specifications of materials. It depends on the packaging of different products, and can be added with an oxygen barrier layer as needed to reduce oxygen permeability and extend the shelf life of the product.
Stand up pouch packaging is mainly used in fruit juice pouch, Jelly Pouchs, Sauce Bags and other products. In addition to the food industry, the application of some detergent packaging, daily cosmetics packaging, medical supplies packaging and other products is also gradually increasing.
Classification of Stand Up Pouch
Stand up pouch are basically divided into the following five types:
The general form of doypack a four side sealing form and cannot be re closed or re opened. This type of stand up pouch is generally used in the industrial supplies industry.
A stand up pouch with a spout is more convenient for pouring or absorbing contents, and can be re closed and re opened, which can be considered a combination of a stand up pouch and a regular bottle mouth. This stand up pouch is generally used for daily use packaging, to liquid drink pouch, Fabric Softener packaging, sauce pouches, edible oil packaging, jelly pouchs, etc.
3. Stand up pouch with zipper:
Stand up pouch with zippers can also be re closed and re opened. Due to the fact that 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 different side sealing methods, it can be divided into two types: four side sealing and three side sealing. Four side sealing refers to the fact that the product packaging has a layer of ordinary edge sealing outside the zipper seal when leaving the factory. When using it, the ordinary edge sealing needs to be torn open first, and then the zipper is used to achieve repeated sealing. This method solves the problem of low zipper edge strength and is not conducive to transportation. And the three side sealing is directly used as a zipper edge sealing, usually used to hold lightweight products. Stand up pouch with zippers are generally used for packaging lightweight solids such as candy bag, cookies packaging, jelly pouchs, etc., but stand up pouch with four side can also be used for packaging heavier products such as Rice Packaging and cat litter.
The faux mouth type stand up pouch combines the convenience of a stand up pouch with a spout with the affordability of a regular stand up pouch. The function of the spout is achieved through the shape of the bag itself. However, stand up pouch with a mouth like shape cannot be repeatedly sealed and opened, so they are generally used for packaging liquid, colloidal, and semi solid products that are disposable, such as beverages and jellies.
5. Irregular Shape stand up pouch:
According to packaging needs, various new types of stand up pouch with different shapes are produced by changing the traditional bag shape, such as waistband design, bottom deformation design, and handle design. It is the main direction for the value-added development of stand up pouch.
With the progress of society, the improvement of people's aesthetic standards, and the intensification of competition in various industries, the design and printing of stand up pouch have become increasingly diverse, with more and more forms of expression. The development of irregular shape stand up pouch is gradually replacing the status of traditional stand up pouch.
