Paper feeding mode of portable paper bag machine with square bottom

There are two main types of hand-held paper bag machines with square bottom according to the way of paper feeding: 

one is the drum-type hand-held paper bag machine; 

One is a single-sheet portable paper bag machine. 

Both kinds of paper bag machines have the characteristics of automatic paper feeding, automatic gluing, automatic bottom pasting and automatic output of products. But there are still some shortcomings. 

First, after the finished paper bag is finished, there is an indentation on the front of the paper bag, which affects the appearance of the product; 

Second, the finished paper bag needs to be manually pasted with a base paper at the bottom of the bag to enhance the strength of the bottom of the paper bag;

 Third, the handle of the paper bag needs to be pasted by hand; 

Fourth, the production efficiency is low, about 40-60 per minute;

 Fifthly, it can adapt to the limited range of paper, and the weight of paper is between 70-200g/m2.
