Self-supporting bags and self-supporting zipper bags are favored by food enterprises

Food packaging not only bears the mission of containing and protecting food, but also should provide consumers with the greatest convenience and ease of use on the premise of minimum impact on the environment. Self-supporting bags and self-supporting zipper bags are popular in the field of food packaging in recent years because of their convenience, ease of use, excellent shelf display and environmental protection.

Self-supporting bag is a flexible packaging bag with a horizontal supporting structure at the bottom. It does not need to rely on any support and can stand on its own regardless of whether the bag is opened or not. Self-supporting bag has excellent shelf display. In addition, in order to meet personalized consumption needs, self-supporting bags can also add personalized design elements, such as handles, curve contours, and resealable zippers, which greatly enhance consumers' desire to buy. At present, self-supporting bags have been widely used in food, juice drinks, absorbable jelly, condiments, pet food and other packaging.

Self-supporting zipper bag refers to the addition of a zipper on the basis of the original soft packaging bag, thus adding resealable function to the packaging bag, so that consumers can repeatedly seal the unfinished food. In developed countries and regions such as Europe and the United States, zipper bags have been widely used in food packaging fields such as meat, cheese, frozen food, nuts, candy and pastries. At present, our independent zipper bags are mainly used in the fields of betel nut and tea. Self-supporting zipper bags used for food packaging mainly include three series: compression type, slide type and zipper strip type.

Although the development history of self-reliant bags and self-reliant zipper bags in China is not long enough, they have shown a good momentum of development. In the near future, these two flexible packaging forms will be more and more widely used in the field of food packaging.
