Title:
PROCESS FOR IMPRINTING PATTERN ON FILM AND DIE THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/134517
Kind Code:
A1
Abstract:
A process for imprinting a pattern on a film comprises the following steps: step 1, stacking a high-temperature resistant film and a thermoformable film; step 2, heating the stacked high-temperature resistant film and thermoformable film; step 3, attaching the thermoformable film that has been heated and softened to the high-temperature resistant film and using a die roll (1) to imprint a pattern on the same; step 4, a surface temperature of the die roll (1) being lower than 30 degrees Celsius, cooling and shaping the thermoformable film that has already been imprinted at the same time as the die roll (1) is imprinting the pattern; and step 5, separating the finished thermoformable film from the high-temperature resistant film, and completing the entire process. The process uses a high-temperature resistant film to improve a process for imprinting a pattern on a thermoformable film, thereby effectively resolving the issue of limitations on the temperature and thickness of thermoformable films. The process can imprint thermoformable films of different thicknesses with deep, distinctive, complex, and diverse patterns, thereby reducing the costs of using different types of machines to imprint patterns. In addition, the high temperature resistant film can be reused multiple times.
