Why Do Milk Jugs Have Circular Indents? It’s to Prevent them from Bursting When Dropped!

Have you ever pondered over the purpose of the circular indentations spotted on your milk jugs? These seemingly insignificant features actually play a crucial role in preserving the structural integrity of the container. Crafted from semi-flexible plastic, the jug’s material is susceptible to shattering or splitting upon impact. However, these circular recesses provide an allowance for minor flexing, thereby mitigating the risk of damage. They cleverly serve as a pressure release system, allowing the jug to expand outwards during sudden pressure changes.

Much like the irresistible rebound of a water balloon after being dropped, a seemingly mundane gallon of milk possesses a similar resilience. The next time you find yourself handling a milk jug, you’ll find it challenging to dismiss this little-known distinctive trait.
