2. Residual adhesion rate: The residual adhesion rate refers to the force of the release paper after one peeling and the second peeling, and the data obtained after calculation mainly reflect the curing effect of silicone oil.

3. Peeling force: The size of the peeling force directly affects the performance of the PET release film.

4. Processing environment: With the increasing progress of various products and the improvement of quality technology, the cleanliness requirements of PET protective films are becoming more and more strict, especially in the electronic film cutting industry
