Dairy products face two main spoilage risks in chilled storage: light exposure can develop oxidised notes, and a weak barrier can shorten refrigerated shelf life. This milk bag-in-box counters both with a silver foil-laminate inner bag for light and oxygen resistance, held inside a paper carton that lets the pack stand upright and stable in a chiller; the format suits mid-to-large dairy sizes around 5L. Its outlet is a butterfly valve: press to dispense, release to stop. That is cleaner than cutting the bag open and keeps the whole bag from being exposed to air after opening; close the valve and the remainder can go back into chilled storage, which fits cafés, bakeries, households and professional kitchens that draw milk as needed. The inner bag is heat-sealed on all sides, with the interface and valve sealed before filling, and it can be stacked and transported inside its carton. Capacity, valve diameter and carton construction are all customisable to your filling line.
