This BIB bag is designed for the transfer, storage and shipping of industrial and food-grade liquids, used with a carton or plastic outer box so filled bags can be stacked and palletised directly. The body is a stand-up pillow shape with flat, strong heat-sealed edges. The outlet can be fitted with a 5L ring-pull oil valve or a spout valve; once the ring pull is opened, a pump head or hose connects straight to the valve, keeping handling contact to a minimum. A welded flange at the fitment keeps the seal reliable when the bag is inverted or laid on its side.
The laminate is based on metallized PET, PET, NY and PE films. The metallized layer acts as the oxygen, light and moisture barrier, while the inner PE layer provides reliable heat sealing and compatibility with the liquid. Thickness and layer combination can be adjusted to suit the product. Printing is done by 1-8 colour gravure printing, with custom artwork or samples accepted, giving saturated colour and clear detail even in small text. Standard volumes run from 100ml to 5L; bag size, valve position and outlet diameter can be tailored to your outer box and filling line, and matching roll film is available.
Typical applications include edible oil, soy sauce, syrup, fruit puree, detergent and lubricant, both for in-plant transfer and final packaging, as well as industrial liquid distribution in the chemical and household care sectors. The custom process usually runs from requirement discussion and sample or drawing confirmation to structural sampling, then batch production after the sample is approved. Our factory is based in Dongguan, Guangdong, with a Class 10000 clean workshop covering film blowing, printing, lamination and bag making in house, at a MOQ of 10,000 pcs. Production is scheduled against the confirmed specification to keep delivery on track.
