In the process of producing packaging bags, the Paper Bag Machine usually has to think about three factors: what kind of paper to choose, what size is it, and what special needs are there for the Paper Bag itself. Take our common hand paper bag for example: its size is usually determined according to the details of the item. The size is composed of length*width*height. The commonly used specifications are folio, three-fold or four-fold paper. Let's talk about what kind of paper to choose. The paper usually chooses coated paper, such as 157G, 200G. If you are packing heavy items, you can use coated paper above 300G. There are also some special patterns that can be printed on jammed paper, which requires lamination to enhance the stiffness of the paper bag. In addition, in terms of patience, kraft paper has the strongest patience and is increasingly used in the production of packaging bags. The main business of our company are: Paper Bag Machine, Paper Rope Machine, Paper Handle Machine, Paper Slitting Machine, Paper Rope and Paper Bag.
