How Bag-in-Box Filling Machines Work

BIB filling machines are ingenious devices designed to precisely transfer liquid products into flexible bags equipped with taps or spouts. These bags typically consist of multilayer films. The films act as protective shields against oxygen, light, and contaminants. Once filled, these bags are conveniently packed into cardboard boxes for effortless transportation and storage.

The adaptability of these machines is remarkable! Various models are available to suit specific needs. Identified by features like the level of automation, bag size, and shape can help separate them apart. Additionally, the tap or spout type and the unique characteristics of the product being filled are another.

But what most have in common are a few key components and functionalities that they all share:

  1. A Bag Supply System: This system provides a steady stream of bags to the filling station. Depending on the machine type, it can be either manual or automatic – working with various operational preferences.
  2. Filling Head: The filling head is the heart of the BIBs, performing all the critical functions. Their main job involves opening, removing air, and introducing and sealing the product. This component can be a single or double head (depending on the required output speed). Finally, it adjusts easily to different tap layouts and bag sizes.
  3. A Filling Valve: Precision in product flow and volume is essential. A filling valve’s role is to control the flow meters, load cells, or timers. Additionally, it introduces nitrogen or other gases into the bag – effectively preventing oxidation and extending the product’s shelf life.
  4. Control Panel: Acting as the brain of the hardware, the control panel oversees and adjusts critical parameters. It ensures that the filling speed, volume, and vacuum levels are all monitored, including the nitrogen pressure. It should also provide a clear interface for any errors or possible interference.
