This BIB bag-in-box is built for bulk filling, storage and cold-chain handling of liquid foods. The bag body uses a stand-up square-bottom or pillow-type construction with reinforced four-side seals and rounded corners, so it holds its shape inside a carton or plastic outer box. The outlet can be fitted with a single spout, twin spouts, a butterfly valve or a press-button valve, each with a sealing gasket at the interface, allowing steady pouring even when the box is inverted or stacked.
The bag is heat-sealed from multi-layer laminated film. Typical structures include PET/AL/PE, PET/VMPET/PE and PET/NY/PE, with a food-contact PE inner layer that provides oxygen and moisture barrier plus puncture resistance. Outer layers accept 1-8 colour gravure printing, reproducing solid blocks, gradients and fine text with good ink adhesion. Capacities range from 100ml to 20L, and bag shape, spout position and dimensions can all be adjusted to your artwork.
Typical applications include pasteurised egg liquid, condensed milk, syrup, jam, juice concentrate, soy sauce, edible oil and other liquid seasonings, as well as sauce distribution for chain restaurants and central kitchens. Our custom process covers sample or drawing review, structural proofing, sample approval, mass production and outgoing inspection. Produced in Dongguan, Guangdong in a Class 10000 clean workshop with an MOQ of 10,000 pcs; matching roll film in the same material is also available.
