1. for various specifications of commercial printing, the number ranges from several hundred to less than 200000, mainly offset printing (or no printing), and the bag is made by printed flat paper:

1) wide-format offset printing machine, monochromatic machine can choose beiren alcohol 08 machine about 400000, two-color can choose alcohol 05 machine about 700000, four-color color printing machine can choose Heidelberg cd102 machine about 9 million, four-open printing machine is not suitable for bag making because paper bags need relatively wide paper, four-open machine can't print, if two sheets of paper are used to make a bag, it will reduce efficiency, and there is no way to use automatic bag making machine, if the money is insufficient, the printing part can also be outsourced to a powerful printing factory, in this way, there is no need to take up equipment investment and buy equipment when the work is stable.

2) Die cutting and creasing. If you use manual bag making or part of the mechanism bag, you need indentation to help make the bag. The machine is about 50000.

A good machine can make 8000 bags in an hour, less than 50000 bags are not worth using, coated paper cannot be used on the machine, and there is no way to finish punching and threading ropes!

2. For large packaging orders, the quantity is more than 100000 to up to one million bags, mainly flexographic printing, using web printing.

) Use a wide-format laminated flexographic printing machine, with a width of about 1 meter, about 1.8 million made in Germany and the United States, and about 200000 made in China. It is OK to buy the domestic one in the early stage. The flexographic printing machine has a simple structure, but the efficiency of the domestic machine is relatively lower than that of the imported machine, and the printing effect is similar.

2) Use web automatic bag making machine, there are German, American, French, Japanese, domestic machines.
