Bag in Box also named BIB is a type of container for the storage and transportation of liquids. It consists of a strong bladder (or plastic bag), usually made of several layers of Metalized film or other plastics such as Nylon (PA), LLDPE, EVOH, seated inside a corrugated board box. The bag is supplied to the ‘filler’ as an empty pre made bag. The ‘filler’ then generally removes the tap (Valve), fills the bag and then replaces the tap. The bags are available as singles for semi-automatic machines or as web bags, where the bags have perforations between each one.
