The hot-pressed kraft paper used in the LAUFFER laminator is made of pure wood pulp through a special process. It is mainly used in the laminating process of PCB, CCL and FPC, and plays the role of heat transfer, buffer, decompression and heat preservation.
 
When laminating or laminating multi-layer board or substrate board of LAUFFER laminator, kraft paper is mostly used as heat transfer buffer. It is placed between the hot plate (Platern) of the laminating machine and the steel plate to ease the heating curve closest to the bulk material. Between multiple substrates or multilayer boards to be pressed. Try to narrow the temperature difference of each layer of the board. The commonly used specifications are 90 pounds to 150 pounds. Since the fiber in the paper has been crushed after high temperature and high pressure, it is no longer tough and difficult to function, so it must be replaced. This kind of kraft paper is a mixture of pine wood and various strong alkalis. After the volatiles escape and the acids are removed, it is washed and precipitated; after it becomes pulp, it can be pressed again to become rough and cheap paper. material.
