Silicone paper and film paper how to distinguish

1. Use tape for testing. Cut a length of tape and stick it to each sheet, then peel it off. It feels good to peel off, and the silicon-coated release film is the one that makes no noise during the peeling process. It is more difficult to peel off the ordinary non-silicon-coated plastic film, which squeaks inside. The process of uncovering. In this way, it is also possible to distinguish whether it is a single-silicon film coated with silicon on one side or a double-silicon film coated with silicon on both sides, and even compare the amount of silicon coated on which side and the peeling rate.

2. Written test. Use a water pen to test, underline the surface of the film, and draw any ink from the surface of the film. Ordinary films will have ink marks of different shades.

In addition, glossy paper and coated paper sometimes look alike, but if they are torn apart by hand, the edge of ordinary paper will only have fiber wool, while coated paper will have some small diaphragms in addition to wood fibers. When tested with tape, the wet paper made noise when the tape was removed, but nothing stuck to the tape, while smooth plain paper stuck to the surface coating and wood fibers.
