The square bottom portable paper bag machine is mainly used for packaging of garment products, packaging of boots, packaging of various gifts, corporate image promotion bags, etc. Because it is easy to carry and easy to degrade, it can recycle recycled paper, reduce air pollution and protect the environment. Therefore, it is one of the most useful green products. The development of paper bag machinery has shown the momentum of integrating electromechanical, gas, liquid, light and magnetism. The production is highly efficient, and the product energy saving and recycling, high-tech practical and intelligent has become a trend.

        There are two main types of square-bottomed paper bag machines on the market: one is a roll-type portable paper bag machine; the other is a single-sheet portable paper bag machine. Both devices are equipped with automatic paper feeding, automatic gluing, automatic paste bottom, and automatic output. However, there are still some shortcomings; first, after the finished paper bag is completed, 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 manually paste a bottom paper on the bottom of the bag to enhance the strength of the bottom of the paper bag; The handle of the paper bag needs to be manually pasted; the fourth is the production efficiency is low, about 40-60 per minute; the fifth is the limited range of paper, the paper weight is between 70-200g/m2. In the shortcomings of the domestic bag making machines, Germany and Japan have basically solved the above problems. The purpose of the development of the GY square bottom paper bag machine is to achieve or approach the world advanced level and promote the development of the domestic square bottom paper bag machine.
