When we eat melon seeds, there is a problem plaguing us, the place that we throw the hulls. If it is no trash can around, we have to throw the hulls into everywhere. Therefore, we slightly change the structure of the package bag. We divide it into two parts, it is seeds bags and garbage bags ,which not only solves the problem of seeds hull, but also protects the environment.
