In the process of producing packaging bags, the paper bag machine usually has three elements to consider: what kind of paper is used; what size is the size; the paper bag itself has special needs.
         Take our common tote bag: its scale is usually determined according to the size of the item. The scale is long * wide * high. The commonly used specifications are split, 3 or 4 open, each one, and There are two kinds of generosity or positiveness.
        Let's talk about the choice of paper. Paper is usually made of coated paper, such as 157G, 200G. If you pack more heavy items, you can use more than 300G coated paper, and some special paper jams can be printed. It is necessary to laminate the film to enhance the hardness of the paper bag. In terms of patience, kraft paper has the strongest resistance and is also increasingly used in the production of packaging bags.

         In the end, there will be some special needs for handbags, etc. After the paper bag machine is manufactured, the adhesive box is worn after the press molding, in order to add the tensile force of the handbag, it is necessary to strengthen the rivet at the rope hole.
