Both of the two ways of making paper bag have their advantages and shortcomings as following:
paper bag by handmade: we can make any size as clients requested and the quality will be better than paper bag by machine. Secondly, to an certain extend, if a company has enough workers, then the clients should not worry about the production capacity. But if not, then it will be a problem to get a large order with urgent production.
paper bag by machine: Paper bag machine has a limitation for size. For example, the middle size, it is just suitable from 18-22cm.But the production is large and fast. So now many factories bring in paper bag machines to improve the production capacity. However, there is one thing you have to know, the quality won't be promised .
Here i just point out the difference for clients to choose from, nothing else.
