QC Packaging is a reliable bag in box supplier offering BIB bags from 1L to 25L for juice, wine, edible oil, sauce, dairy, and drinking water. Our box in bag packaging uses high-barrier flexible inner bags with precision valves and outer cartons. The bag collapses as liquid dispenses with no air intake, extending freshness after opening. Valve options include peristaltic tube caps, spiked adapters, and one-way valves. Custom carton printing available. Compared to plastic drums and metal cans, BIB bags reduce packaging costs by over 30% and save 80% storage space during transport. Widely used in foodservice chains, bubble tea ingredients, boxed wine, and bagged drinking water.

QC Packaging offers a complete range of BIB bag caps and aseptic bag fittings, including peristaltic tube caps, spiked adapters, one-way valves, large flip caps, and base screw caps. Peristaltic tube caps suit low-viscosity liquids. Spiked adapters are our innovative solution replacing peristaltic tubes, saving approximately $0.40 per bag ideal for milk bars. One-way valves maintain negative pressure for oxygen-sensitive products like wine and coffee. Large flip caps handle high-viscosity products like jam, honey, and syrup. All caps are made from food-grade PE/PP, compliant with GB 4806.7 food contact standards. FDA test reports available. Custom specifications supported upon request.
