How to distinguish the release paper, release film and coated paper

First we look at the difference between ordinary plastic film and from the film, and cut a tape, were glued to these films, and then peeled off, it is easy to uncover the feel, the mortgage process, and no sound of is coated release film of silicon, but more difficult to uncover, there is the sound of twittering in the process of exposing no ordinary plastic film coated silicon. This method can also be used to distinguish between a single-sided silicone coated release film of silicon or silicon-silicon double-sided coated release film, which can even compare the number of top coat silicon, the size of the release rate. Another method is to detect water pen, draw at the membrane surface, from the film surface scratch not see any ink, and ordinary film will have shades of ink marks. There plastic coated paper release liner with the same specifications appearance can not tell, but using the above method can also tell the difference between them both. Plain paper and glossy coated paper sometimes look very similar, but if they are torn by hand, at the edge of plain paper only in tearing the hair fiber, wood fiber and coated paper in addition there will be some small small diaphragm. If the tape test, the coated paper in the process of exposing the tape will be noise, but does not glue anything on the tapes, plain paper and glossy paper will stick on the surface of the coating and the wood fibers. Sometimes, silicon coated glassine release paper and have the same size, color coated silicon release paper ordinary lamination, it is difficult to distinguish on the table, but they also have the same release characteristics. However, due to the high-pressure light is made glassine paper, so the paper is more uniform and smooth, and are generally more transparent, so you just like these two have a bright look at the paper in front of transparency and uniformity of the paper is very easy to distinguish it is not, then torn by hand, to see the film is coated paper debris. Highly transparent glassine release paper
