Its existence can effectively protect the leather surface from damage by external factors, such as heat, pressure and friction; ② Providing good stability: The first contact layer usually uses a material with a rough surface, which can ensure that the release paper is firmly attached to the leather surface and is not easy to fall off or shift, thereby ensuring the stability and effect of the fit; ③ Reducing the contact area: The protective scaly surface inside the first contact layer reduces the contact area with the leather while ensuring that it will not slide on the leather. There will also be a certain gap between them to prevent complete contact from causing moisture to be unable to be removed in time, resulting in dampness.
