According to the classification of shape, container bags can be divided into square, round, special-shaped, and so on. What impact will different shapes have on our use or different effects? Nowadays, the two types we commonly use are square and round. It is relatively rare for heterogeneous container bags, but no matter what shape the container bag is, it is customized by our users. But from a usage perspective, circles and squares each have their advantages and disadvantages.



This is a special-shaped container bag in the strict sense. Its advantage is that there is only one gap joint point, unlike the four points of the square container bag. But its shortcoming is also relatively obvious, that is, if all the stress points are concentrated on one point, the force will become larger. Therefore, the number of repeated uses will be reduced.
