People's purchasing power for fast-moving consumer goods (FMCG) is also increasing, and the rapid development of the FMCG market has also driven the rise of the food packaging industry. Nowadays, the types and uses of food packaging are very extensive. Good packaging can establish a high-quality image for products, enhance product competitiveness, and promote Product Sales.

There are many ways to classify food packaging. If classified by technology, it can be divided into: moisture-proof packaging, waterproof packaging, mildew-proof packaging, fresh-keeping packaging, quick-frozen packaging, breathable packaging, microwave sterilization packaging, aseptic packaging, gas-filled packaging, vacuum packaging, deoxygenation packaging, blister packaging, close-fitting packaging, stretch packaging, retort pouch packaging, etc. All of the above packaging is made of different composite materials, and its packaging characteristics meet the requirements of different foods, effectively maintaining the quality and stable functions of the food itself.
 
 
Among them, stand-up pouches are considered one of the classics of modern packaging and are also a relatively novel form of packaging. They have advantages in terms of enhancing product grade, strengthening shelf visual effects, being lightweight and easy to carry, ease of use, waterproof, moisture-proof, anti-oxidation, and sealability. There are five types: ordinary stand-up pouches, stand-up pouches with spouts, stand-up pouches with zippers, spout-shaped stand-up pouches, and irregularly shaped stand-up pouches. They are mainly used in products such as juice drinks, sports drinks, bottled drinking water, suckable jelly, and seasonings. In addition to the food industry, their application in some cleaning products, daily cosmetics, and medical supplies is also gradually increasing.
 
Stand-up pouch packaged products are very convenient for shoppers: because it is soft plastic packaging, it is lightweight and not easily damaged, and shopping bags will not be torn by hard packaging. Waste disposal is easier than bottles. In addition, zipper stand-up pouches can be refilled repeatedly; spout stand-up pouches make food easier to pour; perfect printing quality can help retailers attract consumers' attention; stand-up pouches, cans, and packaging are subject to fewer regulations, etc. Current stand-up pouch technology can already realize many dreams, which is a great market opportunity for soft plastic manufacturers. Some industry insiders also pointed out that with the introduction of high-capacity automated bagging equipment, the development potential of flexible packaging bags is becoming increasingly large.
 
Spout pouches became popular in the 1990s. They are flexible pouches with a horizontal support structure at the bottom and a spout at the top or side. They can stand upright without relying on any support, so they are named spout stand-up pouches.
 
It is a relatively novel form of packaging, with advantages in enhancing product grade, strengthening shelf visual effects, being lightweight and easy to carry, ease of use, freshness preservation, and sealability.
 
Stand-up pouches are laminated from PET/foil/PET/PE structures. They can also have other specifications and materials such as 2 layers or 3 layers, depending on the product being packaged. An oxygen barrier layer can be added as needed to reduce oxygen permeability and extend the shelf life of the product. Ordinary stand-up pouches and general forms of stand-up pouches use a four-side sealing method and cannot be resealed or reopened repeatedly; stand-up pouches with spouts are more convenient for pouring or sucking out the contents and can be resealed and reopened repeatedly. They can be considered a combination of stand-up pouches and ordinary bottle mouths; spout-shaped stand-up pouches combine the convenience of stand-up pouches with spouts and the low cost of ordinary stand-up pouches. That is, the spout function is achieved through the shape of the pouch itself, but spout-shaped stand-up pouches cannot be resealed; irregularly shaped stand-up pouches are various new stand-up pouches with different shapes based on traditional pouch types according to packaging needs, such as waist-cinching designs, bottom deformation designs, and handle designs. This is the main direction of the value-added development of current stand-up pouches.
 
  Stand-up pouch packaging is widely used in soy milk products. Compared with other packaging, stand-up pouch packaging is clean and convenient. You can open it when you want to drink it, and if you don't want to drink it, you can tighten it without wasting it. It can also meet different sterilization and preservation conditions in soy milk production, with a shelf life of 3-5 days under refrigerated conditions and about 1 month under room temperature conditions. At the same time, breakfast soy milk and freshly made soy milk are also starting to use stand-up pouch packaging.
