Our spouts are injection-molded from food-grade PE/PP materials, with dimensional accuracy controlled by precision molds to ensure seamless compatibility with various flexible packages such as stand-up pouches, composite bags, and aluminum foil bags. The one-piece sealing structure, combined with a leak-proof lip design, effectively prevents liquid leakage. Whether for fruit juice, sauces, liquids, or condiments, they deliver the convenient experience of "ready to suck with one opening, no leakage when inverted." Available in custom calibers (16mm-38mm), lengths, and thread specifications, they support surface treatments like matte or transparent finishes, balancing practicality with brand recognition—making them a core accessory for liquid flexible packaging.
Flexible packaging is made from materials such as plastic films, aluminum foil laminates, and paper composites that can be formed into pouches, bags, or roll films. Compared with rigid packaging, it offers lower transportation costs, excellent barrier protection, and greater design flexibility.
