Compared to the dry Bag in Box Packaging process, the manufacturing of liquid BIB is a little more complex. In essence, the bag is made by fusing two layers of the chosen film together, then adding the spout, which, as one might expect, needs to be completely leakproof and able to resist the filling process. The bag is filled with the liquid, then the box is closed. The necessary dispensing spout or valve is attached to the bag, and the box may include a perforated hole that makes it simple to access the spout.
As Bag in Box Packaging technology develops, a growing number of liquid or semi-liquid products are being shipped in BIB containers.
