Many people think out of box about how to change the paper bag. Therefore, there is a new type of paper bag occuring in the market. It looks like a paper bag from it's outside. But when you open the paper , actually it is a box. It is really attractive and interesting design. And many comsumers feel like this new design. It suits the market. Here what i try to say is focus your attention on improving paper bag itself instead of low price comparision. Beacuse in the end, it is just a great loss for facotries, nothing else.
