[0023] As shown in the drawings, the composite PET film comprises an inner layer 1, a connecting layer 3 and an outer layer 2, the inner layer 1 and the outer layer 2 are both PET films, the connecting layer 3 is a mesh cloth, and the inner layer 1 and the outer layer 2 are fixedly connected at both sides of the connecting layer 3 by glue. Figure 1

[0024] The reinforcing structure in the composite PET film of the present application comprises two reinforcing strips one 4 and two reinforcing strips two 5, the two reinforcing strips one 4 are fixedly connected to the inner side of the inner layer 1, the two reinforcing strips two 5 are fixedly connected to the inner side of the outer layer 2, and the connecting layer 3 covers one side of the reinforcing strip one 4 and the other side of the reinforcing strip two 5.

[0025] The connecting layer 3 is a mesh cloth material arranged between the outer layer 2 and the inner layer 1, and the mesh holes on the connecting layer 3 can store an appropriate amount of glue, so that the appropriate amount of glue between the connecting layer 3 and the outer layer 2 can stably fix them, and the appropriate amount of glue between the connecting layer 3 and the inner layer 1 can stably fix them.

[0026] At the same time, the reinforcing strips one 4 and the reinforcing strips two 5 can appropriately improve the strength of the inner layer 1 and the outer layer 2, so as to ensure the stable connection of the inner layer 1 and the outer layer 2 and the relatively high strength of the whole composite PET film.

[0027] The reinforcing strips one 4 and the reinforcing strips two 5 are both mesh cloths.

[0028] The reinforcing strips one 4 and the reinforcing strips two 5 have the same mesh count, and the mesh count of the reinforcing strips one 4 is greater than that of the connecting layer 3.

[0029] Such a structure not only improves the overall strength, but also ensures that the glue is stably immersed between the reinforcing strips one 4 and the inner layer 1 or between the reinforcing strips two 5 and the outer layer 2.​

[0030] The outer layer 2 has the same thickness dimension as the inner layer 1.

[0031] The two reinforcing strips one 4 and the reinforcing strip two 5 located between the two form a reinforcing unit, and the number of the reinforcing units is several, and the several reinforcing units are arranged along the length direction of the inner layer 1.

[0032] The arrangement of the plurality of reinforcing units can effectively improve the overall strength and stability.

[0033] In the two adjacent reinforcing units, the reinforcing strip one 4 in one reinforcing unit is fixedly connected at the inner layer 1, and the reinforcing strip one 4 in the adjacent other reinforcing unit is fixedly connected at the outer layer 2.

[0034] The number of the reinforcing strip two 5 in the same reinforcing unit is several, and the several reinforcing strip two 5 are arranged adjacent to each other.

[0035] Such a structure can make the overall strength uniform.

[0036] The number of the reinforcing strip two 5 is two.

[0037] The width dimension of the reinforcing strip two 5 is the same as the width dimension of the reinforcing strip one 4.

[0038] The gap dimension between the reinforcing strip two 5 and the adjacent reinforcing strip one 4 and the thickness dimension of the connecting layer 3 are matched.

[0039] Such a structure can ensure that the strength of the entire composite PET film is uniform.

[0040] The reinforcing structure in the composite PET film can store an appropriate amount of glue at the connecting layer, so that the inner layer and the outer layer can be stably fixedly connected on both sides of the connecting layer. At the same time, since the inner layer has the reinforcing strip one and the outer layer has the reinforcing strip one, the composite PET film with the reinforcing structure has relatively high strength.

[0041] It can be seen that the reinforcing structure not only effectively improves the strength of the composite PET film, but also has relatively high overall stability, and has high use value.
