[0028] Please refer to Figures 1-5 , the present utility model provides a technical solution: a film-coated paper box for preventing glue opening in a low-temperature environment, including the first main board 1, the first side plate 2, the second side plate 3, the first top plate 4, the baffle 5, the second main board 6, the second top plate 7, the modified PET film 8, the combined plate 9 and the tear line 10;

[0029] For this film-coated paper box, the properties of the modified PET film 8 are improved to prevent the paper shell from opening. The specific implementation method is as follows:

[0030] The main board 1 is set as a square cardboard structure, and one side of the surface of the main board 1 is fixedly connected with a first side plate 2; one side of the surface of the main board 1 is fixedly connected with a second side plate 3, and a first top plate 4 is symmetrically arranged on the surface of the main board 1, and a tear line 10 is arranged on the surface of one of the first top plates 4. The surfaces of the first side plate 2 and the second side plate 3 are both fixedly connected with baffles 5, and the other end of the second side plate 3 is connected with a second main board 6. The surface of the second main board 6 is symmetrically and fixedly connected with a second top plate 7, and modified PET films 8 are fixedly connected to the surfaces of the second top plates 7. One side of the second main board 6 is connected with a combined board 9. The main board 1 and the second main board 6 are symmetrically arranged on both sides of the second side plate 3, and the positions of the second side plate 3 and the main board 1 are correspondingly arranged. The positions of the first side plate 2 and the second side plate 3 are correspondingly arranged, and the inner wall of the combined board 9 is attached to the outer surface of the first side plate 2. The first top plates 4 are symmetrically arranged on both sides of the main board 1. The end of the first side plate 2 is attached to the surface of the second main board 6. The inner wall of the second top plate 7 is attached to the surface of the baffle 5, and the baffle 5 is arranged on both sides inside the second top plate 7. The positions of the two modified PET films 8 are symmetrically arranged on both sides of the second main board 6. The modified PET films 8 are symmetrically arranged on both sides of the second main board 6. The inner wall of the first top plate 4 is correspondingly arranged with the surface of the second top plate 7, and the end of the modified PET film 8 is correspondingly arranged with the position of the first top plate 4.

[0031] Lay the cardboard flat and cut the whole paper box so that the cardboard forms the finished product of the required paper box after cutting, such as Figure 2 , at this time, work on the cut cardboard by a scoring machine to produce indentations between adjacent cardboards, which is convenient for bending them. At the same time, process one of the first top plates 4 through laser technology to form a tear line 10 on the surface of the first top plate 4. At the same time, it is necessary to adjust the modified PET film 8 so that the content of the water-based acrylic resin in the modified PET film 8 reaches 10 - 25%, and the content of the acrylate copolymer reaches 50 - 75%, and the content of other primer components remains unchanged, so as to form a new modified PET film 8. When the modified PET film 8 is formed, it needs to be die-cut, and the die-cutting plate parameters of the modified PET film 8 are modified to a knife height of 23.5 mm, a knife thickness of 0.71 mm, and a die-cutting plate thickness of 18 mm. Then, fix the produced modified PET film 8 on the surface of the second top plate 7 through a laminating machine;

[0032] Bend the creases of the adjacent cardboard sheets. At this time, position the first side plate 2 and the second side plate 3 correspondingly, make the outer surface of the first side plate 2 fit the surface of the composite board 9. At this time, the first side plate 2 and the second side plate 3 are respectively perpendicular to the first side plate 2 and the second side plate 3. Then bend the baffle 5 inward so that the ends of the baffle 5 are correspondingly arranged. Bend the second top plate 7 so that the bottom of the second top plate 7 fits the bent baffle 5. At this time, bend the first top plate 4 so that the bottom of the first top plate 4 fits the surface of the second top plate 7. At this time, one end of the first top plate 4 fits the surface of the modified PET film 8. At this time, the modified PET film 8 and the tear line 10 are arranged in an alternating position. After the paper box is installed, by pulling the tear line 10, the two ends of the tear line 10 lose contact with the first top plate 4. At this time, the tear line 10 is torn off from the surface of the first top plate 4. At this time, one side of the first top plate 4 is fixedly connected to the modified PET film 8, and the other side of the first top plate 4 is connected to the main board 1. At this time, the remaining first top plate 4 and the second top plate 7 can be opened to take out the things inside the paper box.
