Realizing the hazards that are involved in purchasing unpackaged milk, increasingly people are purchasing milk bags, pouches with pasteurized milk, which is processed by dairies with specialized equipment after following to the quality guidelines. The milk is classified depending on the fat content of the milk, toned milk usually has a lower fat content while whole milk has a higher fat content and is used for making ice cream, butter, ghee . Tone milk is usually cheaper than whole fat milk for most major dairy brands in india.

Usually 500 ml and 1000 ml milk bags are available in the market. Compared to other plastic used for packaging, the milk bags used for milk have a thicker grade of plastic as even a small pinhole can result in the leakage and wastage of the milk.

While purchasing a milk bag it is advisable to check whether the milk bag is leaking , because all the milk can leak away, even if there is a very small hole in the milk bag.
