Everyone thinks cotton bags and canvas bags are the same material, right? In fact, although their raw materials are made of pure cotton textile, in the natural environment easy to degrade, and will not pollute the environment. However, they also have a difference, that is, canvas bags are generally thicker than cotton bags.
