Detailed Description
For a clearer understanding of technical features, objects, and effects of the present application, a specific embodiment of the present application will be described with reference to the accompanying drawings. Wherein like parts are designated by like reference numerals.
Due to the defects of the multilayer co-extrusion matte film in the prior art, the application provides a single-sided matte polyester film and a preparation method thereof. In a specific embodiment of the present application, the single-sided matte polyester film includes a polyester base film 1, and one side surface of the polyester base film 1 is provided with a layer of on-line coating matte coating 2, as shown in fig. 1. In another embodiment of the present application, the single-sided matte polyester film of the present application includes a polyester base film 1, one side surface of the polyester base film 1 has a layer of on-line coating matte coating 2, and an off-line protective coating 3 is coated on the outer side of the on-line coating matte coating 2, as shown in fig. 2.
The matte effect of the single-sided matte polyester film is obtained by online coating of the matte coating in the production process of the polyester base film, the original properties of the polyester base film are kept unchanged, and the situation of weakening of the performance after stretching does not exist. In addition, the online coating is to directly coat chemical substances on the film by using an online coater while the film is stretched, so that the stretching production line of the film is not required to be changed, and compared with a multilayer coextrusion process, the online coating is simpler and has lower cost. The online coating reduces the process of rewinding the film once, and has the advantages of higher operation speed, high efficiency and lower cost. In addition, the finished product can obtain an anti-blocking effect without adding anti-blocking particles into the polyester base film due to the existence of the matte coating.
In addition, in the embodiment shown in fig. 2, in order to improve the durability of the on-line coating matte coating 2, an off-line protective coating 3 may be added on the outer side of the on-line coating matte coating 2 in an off-line coating manner, so that the off-line protective coating 3 not only can provide enough protection, but also can fill the area with uneven thickness caused by stretching of the on-line coating matte coating 2, so that the thickness of the whole finished film layer is kept consistent, the problem of inconsistent matte effect caused by uneven thickness of the film layer is avoided, and the texture and durability of the product can be further improved.
As described above, the components constituting the primer of the in-line coating matte coating layer 2 are not formed by coating the surface of the already prepared polyester film, but are coated during the preparation of the polyester base film 1.

In summary, the matte effect of the single-sided matte polyester film is obtained by online coating of the matte coating in the production process of the polyester base film, the original properties of the polyester base film are kept unchanged, and the situation of weakening of performance after stretching does not exist. In addition, the online coating is to directly coat chemical substances on the film by using an online coater while the film is stretched, so that the stretching production line of the film is not required to be changed, and compared with a multilayer coextrusion process, the online coating is simpler and has lower cost. The online coating reduces the process of rewinding the film once, and has the advantages of higher operation speed, high efficiency and lower cost. In addition, the finished product can obtain an anti-blocking effect without adding anti-blocking particles into the polyester base film due to the existence of the matte coating.
