Common commodity paper bags are mainly produced by rotary printing paper bag machines. The production method of the portable paper bag is high in production efficiency. Instead, it is a delicate shopping bag that uses a single sheet of paper and then prints it in color. Finally, the paper bag factory performs manual or semi-automatic machine production. Usually, manual stringing and knotting are used as handles to complete the production of paper bags. The advantage of this shopping bag is that any shape of paper can be made into a portable paper bag. However, this production method has high production efficiency. This type of paper bag is mostly used for some ordinary product packaging, as a gift bag, or as a commercial bag in some commercial activities. Of course, the exquisite and beautiful hand-made paper bag has also become a convenient shopping bag for ladies. Paper bags are the first choice for shopping bags today, but also an extension of corporate image and product advertising.
