Equipped with a special filter sealed in a barrier foil, this big bag allows goods to be vaccum-packed and stored in an inert gas environment.
After filling, any oxygen present is removed via the filter. Once a vacuum has been created, the product inside the bag is charged with inert gas such as nitrogen. Commonly known as modified atmosphere packaging (MAP), this procedure ensures that goods stored in inertised Big Bags have a much longer shelf life.
Modified atmosphere packaging is favoured especially by suppliers of food stuffs since it offers considerable economic benefits such as extended storage periods and transport times. Besides, long-term storage of products makes production planning easier and allows for producing in larger batch sizes. This leads to significant setup time reduction as well as elimination of production waste.
Inertised big bags are preferably used for food products such as:
- milk powder
- cocoa beans
