Aseptic Packaging
Bag-in-box is also used extensively in the packaging of processed fruit and dairy products in aseptic processes. Using aseptic packaging equipment, products can be packed in aseptic packaging. Pasteurised or UHT treated products packed into this format can be "shelf stable", requiring no refrigeration. Some products can have a shelf life of up to 2 years, depending on the type of bag that is used.
The key to this unique system is that the product being filled is not exposed to the external environment at any stage during the process and as such, there is no possibility of a bacterial load being added to the product during the filling process. To ensure there is no contamination from the packaging, the bag is irradiated after the bag manufacturing process.
These packs are typically from 10 to 1200 litres and offer the advantage of cheap, disposable and transport efficient packaging.
