<p>Stand up pouch</p><p><br></p><p><br></p><p>Doypack refers to a flexible packaging bag with a horizontal support structure at the bottom. It does not rely on any support and can stand on its own regardless of whether the bag is opened or not.</p><p><br></p><p><br></p><p>The English name of the self-supporting bag originated from the French company Thimonier. In 1963, Mr. M. Louis Doyen, the CEO of the French company Thimonier, successfully applied for a patent for the Doypack self-supporting bag. Since then, doypack has become the official name application of the self-supporting bag to date. It was widely recognized in the US market in the 1990s, and then popularized worldwide.</p><p><br></p><p>Stand-up pouch is a relatively novel packaging form, which has advantages in many aspects such as upgrading product grade, enhancing shelf visual effect, portability, convenient use, freshness preservation and sealability. The stand-up pouch is laminated with PET/foil/PET/PE structure, and it can also have 2 layers, 3 layers and other specifications. It depends on the different products of the package. An oxygen barrier protective layer can be added as needed to reduce the oxygen permeability. , Extend the shelf life of the product.</p><p><br></p><p><br></p><p>Application range of stand-up pouch</p><p>Stand-up pouch packaging is mainly used in fruit juice drinks, sports drinks, bottled drinking water, smokable jelly, condiments and other products. In addition to the food industry, some products such as detergents, daily cosmetics, and medical supplies are also gradually increasing. .</p><p><br></p><p><br></p><p>Classification of self-supporting bags</p><p>Stand-up bags are basically divided into the following five types:</p><p><br></p><p>1. Ordinary stand-up pouch:</p><p><br></p><p>And the general form of self-supporting bags, using four-sealing form, can not be closed and re-opened, this kind of self-supporting bags are generally used in the industrial supplies industry.</p><p><br></p><p>2. Stand-up pouch with nozzle:</p><p><br></p><p>The stand-up pouch with suction nozzle is more convenient for pouring or sucking the contents, and can be re-closed and reopened at the same time. It can be considered as a combination of stand-up pouch and ordinary bottle mouth. This kind of stand-up pouch is generally used in daily necessities packaging, used to contain beverages, shower gels, shampoos, ketchup, edible oil, jelly and other liquid, colloidal, semi-solid products, such as the famous CiCi.</p><p><br></p><p>3. Stand-up pouch with zipper:</p><p><br></p><p>The self-supporting bag with zipper can also be re-closed and re-opened. Since the zipper is not closed and the sealing strength is limited, this form is not suitable for encapsulating liquids and volatile substances. According to the different sealing methods, it can be divided into four sealing and three sealing. Four sealing means that the product packaging has a layer of ordinary sealing besides the zipper sealing at the factory. The ordinary sealing must be torn before use. The zipper is then used to achieve repeated sealing and opening. This method solves the disadvantage that the zipper has a small edge sealing strength and is not conducive to transportation. The three-sided sealing is directly used as a zipper sealing, which is generally used to hold lightweight products. Stand-up pouches with zipper are generally used to pack some light solids, such as candies, biscuits, jellies, etc., but stand-up pouches with four-sealed sides can also be used to pack heavy products such as rice and cat litter.</p><p><br></p><p>4. Mouth-like stand-up pouch:</p><p><br></p><p>The mouth-like stand-up pouch combines the convenience of a stand-up pouch with a nozzle and the cheapness of a normal stand-up pouch. That is, the function of the suction nozzle is realized by the shape of the bag itself. However, the mouth-like stand-up pouch cannot be sealed repeatedly. Therefore, it is generally used for the packaging of disposable liquid, colloid, and semi-solid products such as beverages and jelly.</p><p><br></p><p>5. Special-shaped stand-up pouch:</p><p><br></p><p>That is, according to packaging needs, new self-supporting bags of various shapes, such as waist design, bottom deformation design, and handle design, are produced by changing on the basis of traditional bag types. It is the main direction of the value-added development of self-supporting bags.</p><p><br></p><p>With the advancement of society, the improvement of people's aesthetic level and the intensification of competition in various industries, the design and printing of stand-up pouches have become more and more colorful, with more and more expressions. The development of special-shaped stand-up pouches has gradually replaced the status of traditional stand-up pouch the trend.</p><p><br></p><p><br></p><p>Huihua flexible food packaging offers free sample of self-standing pouch, welcome to contact us and get sample now.</p>
