Spout pouch products are flexible packaging that replaces rigid packaging with mouth-watering liquid packaging. The structure of spout pouch products is mainly divided into two parts: suction nozzle and stand-up bag. The independent bag part adopts multi-layer composite plastic to meet the requirements of different food packaging performance and barrier properties. The mouthpiece part can be regarded as a general bottle opening with a screw cap on the straw. The two parts are tightly joined by heat sealing to form extrusion, suction, pouring or compression packaging, which is ideal for liquid packaging.

The nozzle pocket fits easily into a backpack or even a pocket, and can shrink in size as the contents decrease, making it easier to carry.

The reasons why spout pouch products are more popular than rigid packaging are: low transportation cost - suction bags are smaller than rigid packaging, which is easier to transport and reduce transportation costs; lightweight and environmentally friendly - suction bags use 60% less plastic than rigid packaging; Less waste of content--the total content taken out from the suction bag accounts for more than 98% of the product, which is higher than that of hard packaging; novel and unique--the suction bag makes the product stand out in the display; better display effect--spout pouch products There is enough surface area for customers to design and promote the brand logo; low carbon emission - the suction bag manufacturing process consumes less energy, is more environmentally friendly, and emits less carbon dioxide.
