Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of base film production, and particularly relates to a preparation method of a reinforced printing base film. BACKGROUND

[0002] Various forms of PET printing films and aluminum-coated films are widely applied to the fields of soft packaging, hard packaging, decorative materials and the like. When applied, these PET printing films or aluminum-coated films often need to be bonded and compounded with another substrate through an adhesive, which involves the bonding among three interfaces: PET film-ink layer or aluminum-coated layer-adhesive layer-second substrate, and a high adhesion between the ink layer or aluminum-coated layer and the PET film is required.

[0003] With the gradual expansion of the application range of the PET printing film and the diversity of the inks and adhesives used, the adhesion of the ink layer to the surface of the film is required to be higher and higher. In particular, some PET printing films that need to be compounded at high temperatures have the problem of strength reduction of the printing layer after compounding; and the two-component adhesive used for compounding has a certain degree of shrinkage stress during curing, which causes the adhesion strength of the printing layer to be reduced after the curing of the compounded film. The causes of these problems are that the internal stress of the ink layer is generated due to the deformation of the ink layer during compounding or curing, which reduces the adhesion of the ink layer. This problem is difficult to solve by means of corona treatment. Therefore, we specially design a preparation method of a reinforced printing base film. SUMMARY

[0004] The purpose of the present application is to provide a preparation method of a reinforced printing base film to enhance the performance of the base film.
