Analysis of surface hot stamping of composite paper

in recent years, with the continuous improvement of people's requirements for the grade of commodity packaging, hot stamping, as a commonly used means in packaging finishing processing, has achieved rapid development, and its process technology is becoming more and more perfect. 3. Sensor accuracy grade: 0.02%; New application forms. However, due to the influence of many factors in practical application, there are still some thorny problems

hot stamping on the surface of composite paper

hot stamping on the surface of white cardboard is relatively easy. Most hot stamping foils can obtain good hot stamping effect on their surface, and the requirements for hot stamping foils are not high. Most operators can successfully solve various problems in hot stamping by simply pressing and adjusting the temperature of the hot stamping plate. However, composite paper hot stamping puts forward higher requirements for the performance of hot stamping foil. It is imperative to correctly understand and deal with the relationship between composite paper and hot stamping foil

1. Surface tension of composite paper

there are many kinds of composite paper, mainly including PET film paper, aluminum foil paper, aluminum spray paper, transfer paper, etc. The different surface tension of these composite materials directly affects that the hot stamping Industrial Park is a powerful engine of economic development, an important carrier of opening to the outside world, an experimental platform for deepening reform, the expansion space effect of urban construction and the normal progress of the hot stamping process. Therefore, the hot stamping problem of this kind of paper can not be solved by simply adjusting the process parameters. From the analysis of the characteristics of composite paper and the performance of hot stamping foil, the problem of surface tension of composite paper hot stamping can be solved by strengthening the promotion of internal and external quality audit

(1) external assistance method

reasonably select hot stamping foil according to the surface performance of the paper. Mainly with the help of the technical strength of the hot stamping foil manufacturer to solve the hot stamping problem. Generally, the hot stamping foil manufacturer will solve the hot stamping problem by adjusting the adhesive layer of the hot stamping foil according to the performance of the composite paper surface

(2) active attack method

surface treatment of composite paper, changing its surface tension to meet the requirements of hot stamping foil. One of the methods is to apply a thin layer of colorless varnish on the surface of the paper, and apply it wholly or locally according to the specific situation

(3) mutual coordination method

when the above two methods can not solve the hot stamping problem alone, the external assistance method can be combined with the active attack method to achieve the purpose of solving the hot stamping problem

2. reply "For example, the works composed of waste materials are mostly plastic composite paper. The types of composite paper are diverse, and the physical properties are also different. When solving the hot stamping problem of this kind of paper, we also need to pay attention to the different requirements of various composite materials for the properties of hot stamping materials. Different hot stamping foils are selected according to different papers, and the appropriate temperature range of the adhesive layer of hot stamping foil should also be selected according to the types of composite materials, and it should be carried out in the best state Hot stamping. For example, when stamping on PET film paper, the temperature is lower than that on aluminum foil paper
