5-Gallon Dual-Valve BIB Bag for Hot Coffee and Juice Concentrate Liquid Packaging

Within a bag-in-box (BIB) system, the valve pouch is the liquid-holding and dispensing component. The pouch can be built with four-side seals or pillow-style edges, while two screw-cap valves sit at the top: one connects to filling equipment and the other serves as the dispense outlet. Each valve base is heat-sealed to the laminate for a secure bond. Once the cap is opened, product flows out directly and air ingress is minimised. This makes the format well suited to bulk liquids that are stored and drawn off in stages, typically placed inside a carton or drum as part of a complete bag-in-box pack.

Film options include PET/AL/PE, PET/VMPET/PE and PA/PE laminates. The barrier layer and gauge can be matched to the fill, helping balance oxygen protection, light blocking and drop resistance. Up to 1-8 colour gravure printing is available on the surface, with controlled image depth and colour consistency for brand logos, flavour identification and usage instructions. Capacities span 100ml to 20L, with 1L, 3L and 5L among the common choices. Bag construction, valve diameter and dispensing method can all be customised.

Typical contents include coffee concentrate for hot drinks, freshly squeezed juice, slush syrup, sugar syrup, dairy and a range of liquid seasonings. The bags also work well for portion packing in food processing plants and central kitchens operated by restaurant chains. The custom process is simple: submit a sample bag or artwork, agree on material, capacity, print and valve specification, then approve a pre-production sample before volume manufacturing. Our Dongguan, Guangdong factory operates a Class 10000 cleanroom, accepts orders from 10,000 pcs, supports sample- and artwork-based customisation, and can supply matching roll film in the same material.
