Bag in Box
In packaging, a bag-in-box or 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 metallised film or other plastics, seated inside a corrugated fiberboard box. The bag is supplied to the 'filler' as an empty pre made bag. The 'filler' then generally removes the tap, fills the bag and 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. These are used on automated filling systems where the bag is separated on line either before the bag is automatically filled or after.
Description
Bag Types:
●Flat pouch ●Stand up pouch
Uses of BiB:
The BiB has many common commercial applications. One of the most common uses of BiBs by commercial users are to supply syrup to soft drink fountains and to dispense bulk supplied condiments such as ketchup or mustard in the foodservice industry specifically in fast food outlets. BiB technology is still used for its original application of dispensing sulfuric acid for filling lead-acid batteries in garages and dealerships. As explained further below, BiBs have also been implemented for consumer applications like boxed wine.
For commercial syrup applications, the customer tears a pre-scored opening at one end of the box and connects a compatible connector to a fitment on the bag to pump out its contents. The fitment itself contains a one-way valve which opens only with pressure from the attached connector and which prevents contamination of the syrup in the bag. For consumer applications like boxed wine, there is a tap already present on the bag, so all the consumer has to do is locate the tap on the outside of the box.
Advantages of BiB:
●Bag in a box packaging is liked by producers because it is inexpensive.
●Seen from the environmental perspective, a bag also has benefits.
●The bag allows contents of 1.5–1000 liters, so that less packaging or labeling is required.
●The material it is made from is lighter than the other plastic alternatives providing it with a better carbon footprint.
●The bags can be filled from chilled product temperatures up to 85 degrees Celsius.
