Heat Transfer Film For Mobile Phone Case

PET thermal transfer film for mobile phone cases is a film material specially used for transferring patterns, text or logos on the surface of mobile phone cases. Through thermal transfer technology, the pre-printed pattern is transferred from the PET transfer film to the surface of the mobile phone case, which is widely used in the decoration and brand logo of various mobile phone cases, such as mobile phone cases made of TPU, PC, silicone and other materials.

Working principle
The working principle of PET thermal transfer film for mobile phone cases is to transfer the pattern from the transfer film to the surface of the mobile phone case by heating and pressure. The specific process is as follows:

Design and printing: Design the pattern according to the needs, and use special inks and processes to print the pattern on the PET transfer film.
Preheating stage: Heat the transfer film and the surface of the mobile phone case to a predetermined temperature in a heating device.
Transfer stage: The transfer film is tightly attached to the surface of the mobile phone case through a pressure device, so that the ink is transferred from the transfer film to the mobile phone case.

Cooling stage: After the transfer is completed, the surface of the mobile phone case cools down and the pattern is firmly attached to the surface of the shell.
