This liquid valve pouch is designed for medium and large liquid packaging, such as juice and drinking water. It uses a stand-up pouch body with a widened bottom gusset, so the bag stands firmly and stacks well in cartons. A food-grade plastic valve is fitted at the top, compatible with common filling equipment, giving smooth dispensing and reliable screw-cap sealing. The four-side seals are heat-reinforced with rounded corners to reduce leakage and bag damage during filling, transport and storage, suiting 1.5L and 3L formats.
The pouch body is built from food-grade multilayer laminated film. Depending on the contents and required shelf life, structures such as PET/AL/PE, PET/VMPET/PE or NY/PE can be selected to balance oxygen barrier, light protection and drop resistance. Printing is done by 1-8 colour gravure printing, giving clear image detail, stable registration and options for matte, gloss or spot effects. Standard capacities range from 100ml to 5L, and pouch style, valve diameter, spout type and roll width can all be adjusted. Matching roll film in the same material is also available.
These valve pouches are widely used for concentrated juice, drinking water, fruit pulp, sauces, detergents and similar liquids, as well as for portioning and distribution in catering, chain stores and e-commerce channels. The custom process is straightforward: send us your sample or artwork, confirm the structure, material and print file, then approve a proof before mass production.
