5. A method of using a casting machine for producing a CPP film according to any one of claims 1 to 4, characterized in that: It comprises the following steps: S1, material distribution and stirring: firstly, the powdery raw materials, the binder, the plasticizer and the dispersing agent are put into the inside of the feeding hopper at a ratio of 3:1:1:1, pass through the feeding port (4005), fall into the inside of the tank body (4001), and the output end of the first motor (4003) drives the stirring shaft (4004) to rotate at a constant speed, so that the different powders in the tank body (4001) are mixed, and after stirring for 1-2h, the first electromagnetic valve (4006) is opened through electric signal transmission, so that the fully mixed powders fall into the bottom bin (4002); S2, mixed liquid mixing: by opening one of the second solenoid valve (5005) and electric gate valve, so that the inside of the bottom bin (4002) mixed powder along the telescopic tube (5004), into the inside of the drum (5002), and open the valve (5008), so that one end of the solvent source, and add the appropriate amount of solvent inside the drum (5002), so that the powder is dissolved, wherein, by starting the second motor (5007), so that its output end of the telescopic tube (5004) one end of the telescopic activity, until the telescopic tube (5004) one end and the second solenoid valve (5005) side of the paste, so as to guarantee the sealing between them, and then by starting the second motor (5007), so that its output end drive drum (5002), facilitate the mixing of the solution inside the drum (5002), so as to form a certain viscosity of the slurry; S3, homogenization: after S2 step, and cooperate with the flow guide of the feed pipe (6004), so that the slurry into the inside of the box (6001), and keep static state, so that it is homogeneous, after 2~3h time, so that the slurry water quality stratification, and then by starting the pump (6002), so that the viscous slurry flows to the inside of the discharge pipe (6003), until the delivery to the discharge tank (7001) inside; S4, scraping coating: by the discharge tank (7001) bottom uniform discharge, so that the surface of the base tape (1100) laid a layer of uniform slurry, and by rotating knob (7004), and adjust the height of the scraper (7002), so that the scraper (7002) on the slurry, so as to form a specified thickness of the film primary product; S5, hot air drying: by the conveying function of the conveyor (100), so that the base tape (1100) drive the film primary product to the bottom end of the air box (8001), and by starting the fan (8004), so that the preheating of the explosion-proof glass tube (8002) heating treatment, so as to form a specified stable hot air, and the film primary product drying treatment, wherein, the heating of the electric heating wire (8003) is controllable operation; S6, quantitative cutting: after S5 step, so that the film primary product becomes green tape, and pull it to the top of the receiving table (200), and then by starting the cylinder (9004), so that its output end of the lifting plate (9002) is pressed, until the bottom end of the cutter (9003) on the side of the green tape contact, and the cutting processing, so as to facilitate the bottom of the receiving table (200) placed in the specified size of CPP film products; S7, stack collection: by the CPP film products after cutting and stacking, and reach the specified height, and then outer packaging, so that it is a specified number of packaging concentrated products.
