High-Barrier BIB Bag-in-Box Pouch with Butterfly Valve & Double-Gusset Base for Juice, Water & Concentrates | 100ml–5L

Designed for high-barrier liquid handling from filling through dispensing, this BIB pouch starts from a stand-up format and gains its stability from a double-gusset base fold. Once filled, it can sit upright, which simplifies case packing, storage and shipping. The top can be fitted with either a butterfly valve or a spout. The valve seat is heat-sealed to the pouch body, producing a flat, strong bond; liquid flows out smoothly and stops cleanly, making the pack suitable for repeated use. The construction can be fine-tuned around a customer's filling equipment and usage pattern to balance pressure resistance with leak prevention.

The pouch body is typically produced from aluminum foil laminated film, with common multi-layer builds such as PET / foil / nylon / PE. These structures provide strong oxygen and moisture barrier, helping reduce the impact of light and air on the contents. Outer surfaces accept 1-8 colour gravure printing, delivering clear image depth and stable registration for brand graphics and product details. Capacities cover 100ml to 5L, while pouch dimensions, valve diameter and dispensing style can be customised project by project. Matching roll film in the same material is also available.

Applications include juice, fruit concentrate, mineral water, tea drinks, sauces and edible oil, along with portioning of industrial and household liquids. Custom projects move from an initial requirements discussion to sample or artwork confirmation, then structural prototyping, and finally volume production, with a dedicated contact throughout. Manufacturing takes place in Dongguan, Guangdong, in a Class 10000 cleanroom. The MOQ is 10,000 pcs, and production and delivery are scheduled according to the run plan.
