The structure of the spout bag is mainly divided into two parts: the spout and the stand-up bag. The stand-up bag part is consistent with the ordinary four-edge stand-up bag in structure, but generally uses composite materials to meet the requirements of different food packaging. The spout part can be regarded as a general bottle mouth with a straw. The two parts are closely combined to form a beverage packaging that supports sucking, and because it is a soft package, there is no difficulty in sucking, and the contents are not easy to shake after sealing. It is a very ideal new beverage packaging.

The biggest advantage of the spout bag over common packaging forms is portability. The spout bag can be easily put into a backpack or even a pocket, and the volume can be reduced as the contents are reduced, making it more convenient to carry. At present, the soft drink packaging on the market is mainly in the form of PET bottles, composite aluminum paper bags, and cans. In today’s increasingly homogeneous competition, the improvement of packaging is undoubtedly one of the powerful means of differentiated competition. The spout bag combines the repeated packaging of PET bottles and the fashion of composite aluminum paper bags. At the same time, it also has unparalleled advantages in printing performance over traditional beverage packaging. Due to the basic shape of the self-supporting bag, the display area of ​​the spout bag is significantly larger than that of the PET bottle, and is better than the packaging of the Tetra Pak pillow that cannot stand. Of course, since the spout bag belongs to the category of soft packaging, it is not currently suitable for the packaging of carbonated beverages, but it has unique advantages in juice, dairy products, health drinks, jelly foods, etc.
