Future development prospects of stand-up pouches

People's purchasing power for fast-moving consumer goods is also growing, and the rapid development of the fast-moving consumer goods market has also led to the rise of the food packaging industry. Nowadays, the types and uses of food packaging are very wide, and good packaging can make products establish a high-quality image, improve product competitiveness, and promote product sales.   There are many ways to classify food packaging. According to the technical classification, it can be divided into: moisture-proof packaging, waterproof packaging, mildew-proof packaging, fresh-keeping packaging, quick-freezing packaging, breathable packaging, microwave sterilization packaging, aseptic packaging, inflatable packaging, vacuum packaging, deoxygenation packaging, blister packaging, paste Body packaging, stretch packaging, retort bag packaging, etc. The above-mentioned various packages are all made of different composite materials, and their packaging characteristics are corresponding to the requirements of different foods, which can effectively maintain the quality and stable functions of the food itself.     Among them, the stand-up pouch is considered to be one of the classics of modern packaging, and it is also a relatively novel packaging form. Take advantage of. There are five types of stand-up pouches: ordinary stand-up pouches, stand-up pouches with suction nozzles, stand-up pouches with zippers, spout-like stand-up pouches, and special-shaped stand-up pouches. In jelly, condiments and other products, in addition to the food industry, the application of some washing products, daily cosmetics, medical supplies and other products has gradually increased.   Products packed in stand-up pouches are very convenient for shoppers: because it is a soft plastic package, it is light in weight and not easily damaged, and the shopping bag will not be broken by hard packaging, and it is easier to waste than bottles. Plus zip-up pouches can be refilled; nozzle pouches make food easier to pour; perfect printing quality can help retailers in order to attract consumers' attention; stand-up pouches, cans, packaging are less restricted by regulations and more. The current stand-up pouch technology can already realize many dreams, which is an excellent market opportunity for soft plastic manufacturers. Some people in the industry also pointed out that with the introduction of high-capacity bagging automation equipment, the development potential of flexible packaging bags is increasing.   The nozzle bag became popular in the 1990s. It is a soft packaging bag with a horizontal support structure at the bottom and a suction nozzle on the top or side. It can stand on its own without any support, so it is named as a nozzle stand-up bag.   It is a relatively novel form of packaging, which has advantages in improving product grades, enhancing shelf visual effects, carrying light, easy to use, fresh-keeping and sealability.   The stand-up pouch is made of PET/foil/PET/PE structure laminated, and can also have 2 layers, 3 layers and other materials of other specifications. It depends on the different products of the package. The oxygen barrier protective layer can be added as needed to reduce the oxygen permeability. , extending the shelf life of the product. Ordinary stand-up pouches and general forms of stand-up pouches are in the form of four-sealed edges, which cannot be re-closed or re-opened; stand-up pouches with suction nozzles are more convenient to dump or absorb the contents, and can be re-closed and re-opened at the same time. The combination of ordinary bottle mouth; the imitation mouth type stand-up pouch combines the convenience of a stand-up pouch with a suction nozzle and the cheapness of an ordinary stand-up pouch, that is, the function of the suction nozzle is realized through the shape of the bag body itself, but the imitation mouth type stand-up pouch cannot be repeated. Sealing and opening; special-shaped stand-up pouches are new stand-up pouches of various shapes produced by changing on the basis of traditional bag types according to packaging needs, such as waist design, bottom deformation design, handle design, etc. main direction of development.   The packaging form of stand-up pouches is widely used in soy milk products. Compared with other packaging, the packaging of stand-up pouches is clean and convenient. You can open it if you want to drink it, and screw it up if you don’t want to drink it without waste. And it can meet the different sterilization and preservation conditions in the production of soymilk, not only 3 to 5 days under refrigerated conditions, but also about 1 month under normal temperature conditions. At the same time, soymilk for breakfast and ready-made soymilk also began to be packaged in stand-up pouches.

How to distinguish whether the plastic packaging bag is PE or PVC material?

We all know that there are many kinds of materials for plastic packaging bags, but the most common materials are PE and PVC. PE plastic packaging bags are mainly made of polyethylene (Polyethylene), which has excellent low temperature resistance, good stability, and can withstand the erosion of most acids and alkalis. PVC plastic packaging bag is mainly made of polyvinyl chloride resin as the main raw material, which is a kind of plastic bag processed with PVC film. It has the characteristics of light weight, heat insulation, heat preservation, moisture resistance and flame retardant. So how do we distinguish whether the plastic packaging bag is PE or PVC? There are mainly the following 4 methods. Identification method: 1. Touch method When you touch the surface of plastic packaging bags, generally PVC plastic bags are sticky and astringent, while PE plastic bags are milky white, translucent and smooth to the touch. 2. Jitter method You can shake the packaging bag with your hands. If it can make a crisp sound, it is usually a PE plastic bag; if the sound is small and dull, it is a PVC plastic bag. 3. Combustion method If conditions permit, the method of burning can also be used to identify PE and PVC materials. Generally speaking, the flame is blue, the upper end is yellow, and the paraffin odor when burning is the PE plastic packaging bag; it is difficult to burn, the flame is yellow, the upper end is green, and the pungent hydrochloric acid odor is the PVC plastic packaging bag. 4. Immersion method First immerse the plastic packaging bag in water, press it into the water by hand, the PE plastic that can surface, and the PVC plastic that sinks to the bottom (the density of the PE plastic packaging bag is lower than that of water, and the density of the PVC plastic packaging bag is higher than that of water; normal temperature are about 0.92g/cm3 and 1.4g/cm3 respectively). Regarding the question of how to identify whether the plastic packaging bag is made of PE or PVC, today's Zhitu packaging? The editor will introduce it here. I believe that through these four methods, it can help everyone quickly identify the material of the packaging bag.
