What is Bag-in-Box?

It is the commercial adaptation of the age old idea of a collapsible liquid carrier. The principle is simple but effective. By using an oxygen impermeable bag, and ensuring that all air is extracted from within the bag during the filling operation, the contents of the bag will remain in good condition irrespective of whether any of the liquid is withdrawn through the special dispenser. As the bag collapses when the contents are dispensed, an even flow is ensured so that no contents can be trapped in the folds of the bag. The outer container which holds the collapsible bag has an aperture through which the dispenser is positioned, this makes the whole package convenient, lightweight and secure.

What are the advantages?

The packer has the benefit of less warehouse space for packaging before filling, more flexibility in designing his filling area with individual machines, in-plant labelling is eliminated and there are distinct gains in load space and weight.

Its basic rectangular shape offers the ideal opportunity for bold graphics to enhance shelf appeal. Consumer advantages are apparent in both domestic and catering packs where the design of the dispenser ensures that operation will be simple, secure and reliable. It allows the contents to pour smoothly and precisely at both ambient and chilled temperatures. The convenient handling, operation and storage of the cask (in a refrigerator if required) combine to give ideal bulk packaging wherever it is used.
