A good ppgi coil substrate is 0.02~0.05mm, and the thickness of the coating or coating is usually less than 0.15mm. Because the thickness of the substrate is very important from the perspective of affecting the use time of ppgi coil. However, some manufacturers make changes in the substrate and ppgi coil coating or film. They reduce the thickness of the substrate, but increase the thickness of the peritoneum to reduce the production cost of ppgi coil, which greatly reduces the service life of ppgi coil.
