The aluminum spout pouch is a water-spraying liquid package that replaces the rigid package in the form of a flexible package. The structure of the aluminum spout pouch is mainly divided into two parts: the nozzle and the self-supporting bag. The stand-up bag is made of multi-layer composite plastic materials to meet the requirements of different food packaging performance and barrier performance. The nozzle part can be regarded as an ordinary bottle mouth with a straw cap screwed on. The two parts are tightly combined by heat sealing (PE or PP) to form a liquid package that is squeezed, sucked, poured or pressed out, which is a very ideal new type of liquid packaging.

Compared with the ordinary packaging form, the biggest advantage of the aluminum spout pouch is that it is easy to carry. The mouth pocket can be conveniently placed in a backpack or even a pocket, and the volume can be reduced with the content, making it more convenient to carry. Soft drink packaging on the market mainly includes PET bottles, composite aluminum paper bags, and pop-top cans. In today's increasingly obvious homogeneous competition, the improvement of packaging is undoubtedly one of the powerful means of differentiated competition. The spout bag combines the repetitive packaging of PET bottles with the fashion of composite aluminum paper bags. At the same time, it also has the incomparable advantages of traditional beverage packaging in terms of printing performance. Due to the basic shape of the self-supporting bag, the aluminum spout pouch has an obvious display area, which is larger than a PET bottle and better than a Tetra Pak pillow that cannot stand. High temperature sterilization, long shelf life. It is also made from a single recyclable low carbon composite material and is the most ideal sustainable solution for liquid packaging. It has unique advantages and wider applications in the fields of fruit juice, dairy products, soy milk, vegetable oil, health drinks, jelly food, pet food, food additives, traditional Chinese medicine, daily chemical products, cosmetics and other fields.
