Self supporting bag is a kind of soft packaging bag with horizontal support structure at the bottom, which can stand on its own without any support. Self supporting bag was invented by European M. Louis Doyen. It was widely recognized in American market in 1990s and then popularized all over the world.

This is an innovation in the packaging industry. With its unique design and function, it has a strong shelf impact, causing a strong sensation in the industry, and is expected to occupy the commanding height of the flexible packaging market.

Self supporting bag is a relatively new packaging form, which has advantages in improving product grade, enhancing visual effect of shelf, portable, easy to use, fresh-keeping and sealability. The self-supporting bag is made of PET / foil / PET / PE structure, which can increase the oxygen barrier layer according to the needs, reduce the oxygen permeability rate and prolong the shelf life of the product. The design with nozzle can be sucked or squeezed for drinking, and a repeatable screw cap device is attached, which is convenient for consumers to carry and use. Whether opened or not, the self-supporting bag packaging products can be upright on the horizontal surface like a bottle, which liberates the hands of consumers. The production cost of self-supporting bags is significantly lower than that of cans, plastic bottles or glass bottles, and the transportation and storage costs are also significantly reduced. Compared with the bottle, this package has better insulation, and the product can be quickly cooled and can maintain low temperature for a long time. In addition, there are some value-added packaging design elements, such as handle, curve contour, laser drilling, etc., which improve the attractiveness of self-supporting bags.
Self supporting bag packaging is mainly used in fruit juice drinks, sports drinks, bottled drinking water, absorbable jelly, condiment and other products. In addition to the food industry, some washing products, daily cosmetics, pharmaceutical products and other products are gradually increasing. Self supporting bag packaging adds color to the colorful packaging world, with clear and distinct patterns standing on the shelf, reflecting the excellent brand image, and more easily attracting the attention of consumers, and adapting to the modern sales trend of supermarket sales. Once customers have used it, they can know the beauty of it, which is favored by the majority of consumers. With the advantages of self-supporting bag packaging being understood by more consumers, and with the continuous strengthening of social awareness of environmental protection, it will become a trend to replace bottle and barrel packaging with self-supporting bag packaging instead of traditional soft packaging which can not be sealed again. China's packaging machinery industry is also closely following the trend of self-supporting bag packaging promotion. Many machinery and equipment enterprises have launched self-supporting bag filling and capping packaging machine, and its main performance and indicators are close to the international level. The working process of this kind of equipment includes: automatic bag transportation, vacuum pumping, automatic positioning filling, automatic capping, capping, capping, automatic withdrawing and self-supporting bag, which will replace the traditional soft packaging

Packaging adds color to the rich and colorful packaging world. Clear and distinct patterns stand upright on the shelf, reflecting the excellent brand image.

Many machinery and equipment enterprises have launched self-supporting bag filling and capping packaging machine, and its main performance and indicators are close to the international level. The working process of this kind of equipment includes: automatic bag transportation, vacuum pumping, automatic positioning and filling, automatic capping, capping, capping, automatic bag withdrawing and liquid level control. Automatic control of the whole process can also be completed in the purification room. Air purification system and PLC man-machine interface control system can be equipped to connect with CIP cleaning system. Due to the good market effect of self-supporting bag packaging and the endless emergence of self-supporting bag packaging products, more and more enterprises are committed to the research and development of this kind of filling machine. Each enterprise mainly relies on its own experience, on the basis of absorbing foreign advanced technology, and according to the domestic characteristics, independent innovation research and development, so that the products have unique characteristics and occupy a certain market share.
The perfect standard system is helpful to improve the product quality level and product grade, and standardize the market order. However, at present, there is no perfect national or industrial standard for the self-supporting bag filling and capping machine. According to the standard formulation and revision plan, the National Packaging Machinery Standardization Technical Committee is responsible for organizing and formulating the industry standard of self supporting bag filling and capping packaging machine. The standard has been published in China packaging standards website industry survey, relevant enterprises can log on the website to put forward suggestions and opinions for the development of standards, and promote the development of industry standards that meet the requirements of industry development and lead the healthy development of the industry. We are looking forward to the introduction of the standard of self-supporting bag filling and capping packaging machine, accelerate the realization of serialization, standardization and generalization of this kind of equipment, and make it develop rapidly on a stable and solid basis
