This 5 kg gochujang bag-in-box is positioned for Korean sauce factories that need clean filling, controlled dosing and a compact bulk format. The inner bag can be specified in PET/VMPET/PE or PET/AL/PE high-barrier laminate, with food-contact grade film selected for gochujang's viscous, fermented character. A wide-mouth spout supports filling and dispensing, while the carton protects the bag during storage and transport. The flexible bag collapses as product is drawn, helping limit headspace and exposure to oxygen, moisture and odours. Available capacities can be adjusted around 3–20 kg for different production batches, and the fitment can be matched to manual or semi-automatic filling lines. This bag-in-box format suits gochujang, soy sauce and kimchi paste producers seeking practical bulk packaging from a Guangdong flexible-packaging factory with a 15,000 m2 clean workshop.
Branding can be handled through 10-colour rotogravure printing on the film or through printed outer cartons, depending on the artwork and pack design. We can support matte, gloss or metallized finishes and keep critical areas clear for fill-level and lot-code marking. For gochujang buyers in South Korea, the inner bag and fitment are specified as food-contact grade, with odour-barrier laminate options to help protect fermented aroma. Small-to-mid MOQs are available: from 3,000 pcs per size/design for standard fitments, with custom print quantities confirmed after artwork review. Sampling is kept practical—pre-production samples using available film and spout options can be prepared for filling trials, and artwork proofs are checked before cylinder or plate production. Please share your target capacity, spout diameter, filling method and carton style so we can quote a bag-in-box build that fits your line.
Quality control focuses on film lamination, seal integrity and fitment welding before cartoning. The structure can combine PET for printability, VMPET or aluminium foil for barrier, and PE as the food-contact sealing layer; exact gauges are confirmed against your gochujang recipe and expected shelf life. Wide-mouth spouts, dispensing valves and butterfly-style outlets can be discussed for different dosing needs, from kitchen-scale decanting to production-line transfer. Production takes place in a 15,000 m2 clean workshop with 10-colour rotogravure capability, supporting consistent colour and repeat orders. Typical lead time is 15–20 working days after artwork and sample approval, depending on fitment stock and print complexity. This makes the format suitable for Korean food manufacturers needing reliable bulk packaging for gochujang, seasoned sauces and hot-pot bases without overcommitting to large inventories.
