5-20 L Light-Barrier BIB Liner Bag for Cold Brew Concentrate with Clean-Flow Dispense Spout

Our cold brew concentrate liner bag is built as a bag-in-box insert for 5 L to 20 L formats, using a high-barrier PET/AL/PE laminate or PET/VMPET/PE alternative to limit oxygen and light exposure during storage and dispensing. The food-contact grade film and sealed spout area are designed for beverage producers filling concentrates, juices, cream, kombucha and plant milk on compatible semi-automatic or automatic filling lines. A clean-flow dispensing spout supports bag-in-box use, while the flexible liner collapses as product is drawn down to reduce headspace. We can quote structures and spout options against your fill temperature, acidity and shelf-life target before sampling.

Printing is produced by 10-colour rotogravure on the outer PET web, allowing brand graphics, filling instructions and lot-coding areas to be registered consistently across repeat orders. Custom printed liner bags are quoted at a 10,000-piece MOQ per artwork and structure; unprinted or stock-structure samples can be discussed for early fit checks. Sampling typically follows artwork approval so the spout, seal strength and film hand-feel can be reviewed before production. We keep the specification factual: film grade, spout size and fitment, fill-temperature range and barrier structure are confirmed against your cold brew concentrate process rather than assumed. The bag is not a stand-up retail pouch; it is a flexible liner intended to be supported inside a box or dispenser.

For West Coast beverage and dairy operations, the liner format supports bag-in-box dispensing and helps protect cold brew concentrate from oxygen pickup and light-driven quality loss between filling and use. The spout and valve options can be matched to common BIB connectors and filling equipment, and aseptic filling compatibility can be reviewed with your process parameters. Lead time is typically 15-25 working days after artwork approval and deposit, depending on spout availability and print complexity. Please share capacity, film structure preference, spout type, fill temperature and expected shelf life so we can propose a workable specification. Guangdong Kody Packaging Products Co., Ltd. runs a 15,000 m² clean workshop in Dongguan with 10-colour rotogravure printing for custom liner bag programs.
