A packaging film mounted on the packaging film seat is sequentially wound around a film guide rod, a floating rod and a film guide roller, then penetrates into the molding mechanism, is conveyed to the special-shaped bag mold along the molding mechanism and then penetrates the punching mold after the direction is changed through a reverse wheel, and left packaging film waste obtained after punching is connected to a paper drawing structure and is finally recovered by the waste recovery mechanism. The machine has the effect of automatically completing the functions of bag making, metering, filling, sealing, slitting, counting and the like and is stable in performance and accurate in detection, and formed errors are small due to intelligent control. According to a tea bag packaged through the structure, the brewed tea bag is applied to the forehead, the cheek, the part around the eye, the nasolabial fold, the U-shaped area and other portions with freckles or wrinkles prone to being generated, the organism can remove peroxide easily, the freckle removal, anti-wrinkle and anti-aging effects are achieved, and meanwhile the residual value of tea can be effectively utilized.
