Oxygen-Barrier 5–25L Coffee Syrup Liner Bag with Butterfly Valve for Bag-in-Box Dispensing

This coffee syrup liner bag is built for bag-in-box beverage operations that need reliable oxygen and light protection. The flexible liner can be specified in 5 L, 10 L, 20 L and 25 L sizes, with multilayer structures such as PET/VMPET/PE or PET/AL/PE to suit different shelf-life and barrier targets. A butterfly valve and fitment are welded into the liner for clean dispensing and controlled flow in bag-in-box systems. Food-contact grade film, strong seals and a clean workshop help support aseptic filling compatibility when the filling line and process are validated. The liner format keeps empty packaging compact, reduces storage space before filling, and allows West Coast coffee syrup producers to ship concentrate efficiently while maintaining a professional dispensing format.

For filling, the liner is supplied with the valve and fitment ready for connection to compatible bag-in-box filling equipment. We can print the outer liner or coordinate a clean unprinted liner for your box graphics, using 10-colour rotogravure printing for clear brand colors, batch information areas and usage instructions. Artwork checks and pre-production samples help confirm valve position, seal integrity and film appearance before mass production. Typical MOQ is 10,000 pieces per size and design, with sampling available for evaluation. Lead times are confirmed after artwork approval, film specification and valve selection. This approach suits beverage producers who need a repeatable coffee syrup package for foodservice, café and retail concentrate programs without overcommitting to rigid containers.

The liner bag is positioned for coffee syrup used in cafés, cold-brew programs, beverage manufacturing and foodservice dispensing. Its bag-in-box format supports gravity or pump-assisted dispensing and helps keep the product enclosed between uses, reducing exposure to air after the box is opened. Oxygen-barrier and light-barrier options are selected according to your syrup formulation, expected shelf life and distribution conditions. We do not claim a fixed shelf life without your product and process validation, but we can recommend film structures and valve options for your trial. For US West Coast buyers, we quote FOB or delivered terms, prepare export cartons and provide samples for filling trials. Please share capacity, valve type, film barrier target, artwork and estimated annual volume for an accurate quotation.
