Often the packaging of the dry fruits is made from cardboard directly. This also helps keep the environment safe as, when it is biodegraded, it does not emit any foul smell that causes any inconvenience. 

Very Light in Weight

The cardboard is very light in weight which means it will not take much time to be degraded. The more the mass of a substance, the more time will it take to be degraded.
