[0002] The packaging bag refers to a bag used for packaging various articles, which is widely used in daily life and industrial production. At present, most of the packaging bags used on the market are made of plastic materials, which are not environmentally friendly. In order to achieve the purpose of environmental protection, paper bags begin to be used on a large scale. However, it is found in actual use that if the paper bag is used to contain articles with high water content or the surface of the article has condensation water, the water will "soak" the paper bag, causing the paper bag to break and unable to be used normally. In order to overcome this problem, a layer of plastic waterproof film is added to the inner surface of the paper bag in the prior art. However, this layer of waterproof film is bonded to the raw material (paper roll) of the paper bag before the paper bag is formed to form a film-coated paper roll. Moreover, cutting waste is generated during the processing of the paper bag, and the cutting waste is a mixture of the paper bag and the waterproof film. Therefore, the two need to be separated again during recycling, but the separation cost is high, and many enterprises directly discard them, resulting in environmental problems for the environmentally friendly paper bag. Therefore, in order to overcome the above problems, a green and environment-friendly packaging bag forming production device and a use method are needed, which can separate the paper bag itself and the waterproof film.

9. The method of using the green and environment-friendly packaging bag forming and producing device according to claim 7, characterized in that, After hot pressing, the suction port on the hot pressing bottom plate and the hot pressing top plate stops working.

10. The method of using the green and environment-friendly packaging bag forming and producing device according to claim 7, characterized in that, When the second suction pipe is slowly extracted, continuous suction is performed, and when the air outlet pipe is slowly extracted, continuous air exhaust is performed.
