The nozzle bag is a revolutionary plastic flexible packaging that is based on the self-supporting bag. It comprises two main components: the self-supporting layer and the suction nozzle. The self-supporting layer is designed with a film at the bottom that enables it to stand upright, while the suction nozzle is made of PE blow molding and injection molding materials that comply with food safety regulations. Manufacturers employ the same composite materials as traditional packaging but with a specific structure to meet the needs of different products.

In contrast, the aluminum foil nozzle bag is made of an aluminum foil composite film that undergoes a series of processes, including printing, compounding, and cutting. The aluminum foil material boasts outstanding properties such as being opaque, silver-white, anti-lustrous, having a good barrier, heat sealing, anti-rotation, high/low-temperature resistance, oil resistance, fragrance retention, no odor, and softness, among others. Manufacturers commonly use aluminum foil for their packaging due to its practicality and high-grade quality, which consumers adore.

Nozzle bags are ideal for packaging liquids such as fruit juice, beverages, detergents, milk, soybean milk, soy sauce, and other products. There are various nozzle types available to accommodate specific products, such as long nozzles for sucking jelly, fruit juice, and drinks, nozzles for washing products, butterfly valves for red wine, and more. Manufacturers can choose from different sizes, colors, and specifications to meet their packaging requirements.
