中文简体In today's era of innovation and convenience, stand-up pouches, as a novel and practical packaging form, are gradually occupying an important position in the market. This kind of soft packaging bag with a horizontal support structure at the bottom has won wide favor among consumers for its ability to stand on its own without relying on any external support.
Recently, many types of stand-up pouches have emerged on the market. They are not only more functional but also show high creativity and diversity in design. Among them, ordinary stand-up pouches are widely used in the field of industrial supplies due to their simple and practical characteristics. This kind of stand-up pouch adopts a four-edge sealing form. Although it cannot be reclosed and opened repeatedly, its sturdy and durable characteristics make it an ideal choice for many industrial products.
At the same time, stand-up pouches with suction nozzles stand out in daily necessities packaging with their convenience. Whether it is beverages, shower gel or shampoo, consumers can enjoy the comfort and convenience brought by the product with just a light suction. This kind of stand-up pouch is not only convenient for pouring or sucking the contents but also can be reclosed and opened repeatedly, which greatly improves the user experience.
In addition, the emergence of special-shaped stand-up pouches has injected new vitality into the packaging market. According to packaging needs, changes are made on the basis of traditional bag types, resulting in new self-supporting bags with various shapes such as waist design, bottom deformation design, and handle design. These designs are not only beautiful and generous, but also more ergonomic, making the product more convenient to carry and use.
It is worth mentioning that self-supporting bags with zippers have also attracted much attention due to their reusable characteristics. Although their closure strength is limited and they are not suitable for packaging liquids and volatile substances, the emergence of two design methods, four-edge sealing and three-edge sealing, effectively solves this problem. When the four-edge self-supporting bag leaves the factory, there is another layer of ordinary edge sealing outside the zipper seal. When using it, you need to tear off the ordinary edge sealing and then use the zipper to achieve repeated sealing and opening; while the three-edge self-supporting bag directly uses the zipper edge sealing as the seal, which is more suitable for light products.
Finally, the imitation mouth self-supporting bag, with its unique design concept, perfectly combines the convenience of self-supporting bags with suction nozzles and the cheapness of ordinary self-supporting bags. Although it cannot be resealed, it is suitable for packaging of disposable liquids, colloids, and semi-solid products such as beverages and jellies, and has won market recognition.
With the continuous popularization and application of stand-up pouches in the market, its innovative design and diverse functions are gradually meeting the diversified needs of consumers. In the future, stand-up pouches are expected to become one of the mainstream products in the packaging market, the innovation and development of the packaging industry.
