[0013] The beneficial effects of adopting the above technology are: strengthening the connection between the horizontal fillet and the vertical fillet, avoiding poor packaging effect caused by too dense gaps, regional damage, and causing the packaging film to fall off.

[0014] As a further improvement of the present invention, the third tear lines and the fourth tear lines are of the same shape and size, and the third tear lines and the fourth tear lines are of the same number and are evenly distributed at the left and right ends of the vertical fillet.

[0015] The beneficial effect of adopting the above technology is that the sealing and tightness of the packaging film is ensured through uniform high-density connection, so that a gap is left between the first packaging film and the vertical fillet, which is convenient for tearing the packaging.

[0016] As a further improvement of the present invention, the upper end of the third packaging film is not completely sealed and a circular gap is left in the center thereof.

[0017] The beneficial effect of adopting the above technology is that during the process of shrink packaging film, if the machine is completely sealed, the air between the bottle seal and the bottle mouth cannot be quickly discharged, which will slow down the packaging speed, and the unexpelled air may also cause the packaging to deform and affect the appearance. By leaving a gap at the top, the air can be quickly discharged, speeding up the packaging speed and preventing the packaging from bulging or deforming.

[0018] As a further improvement of the present invention, the sum of the lengths of the first packaging film, the second packaging film, the third packaging film and the transverse fillet is equal to the length of the packaging object.

[0019] The beneficial effects of adopting the above technology are: ensuring that its length can cover the packaged objects, effectively preventing external factors such as dust, moisture, sunlight, etc. from damaging the packaged objects, and keeping the package clean and complete.
