step 6: preparing an adhesive tape: coating the prepared adhesive layer (5) on the lower surface of the PET original film, coating the standby resin agent on the upper side of the printing layer (3), and finally coating the non-silicon release agent on the upper surface of the resin agent.
9. The low temperature resistant PET film adhesive tape and the preparation method thereof according to claim 8, characterized in that: in the step 2, the printing pattern and the ink color ink of the printing layer (3) are customized according to the requirements of customers.
10. The low temperature resistant PET film adhesive tape and the preparation method thereof according to claim 8, characterized in that: in the step 6, the adhesive layer (5) needs to be cooled after being coated, the resin agent needs to be cooled after being coated, and the non-silicon release agent needs to be cooled after being coated.
