Bag-in-Box A number of design concepts are combined in this packaging
innovation. A liquid, semi-liquid, granular or powdered product is placed in a
plastic bag to prevent sifting of leakage, and the bag is placed in a box for
protection, ease of handling and stacking strength.
Bag-in-Box is used for many products, including wine, milk,
paint, wallboard compound, detergent powders and pet food. The plastic and its
seal must be the proper type for the product.
Many bags incorporate dispensing devices, and the box can have
die-cut holes or perforations to provide access and to position the dispenser
for use.
Advantages of bag-in-box include its light weight in comparison
to other forms of packaging, the rectangular shape that allows full use of
shipping and storage space, the fact that it can be stored flat until it is
used, and the relative simplicity of setup, filling and closure.
As shown, the corrugated structure combines a Center Special
Slotted Container with a full-depth sleeve or liner for added protection and
stacking strength, plus top and bottom pads for extra product protection. The
International Box Codes are 0204 for the box,
0904 for the sleeve, and 0901 for the pads.
The sleeve and pads might be omitted, depending on the gross weight of the
filled package.
The Department of Transportation has authorized bag-in-box styles
for certain acids and other corrosives.
