Preferably, paper is used. In addition, neutral paper
In order to prevent the metal product surface in contact with the surface from being rusted, the chloride ion concentration is 0.01% or less and the sulfate ion concentration is 0.1%.
It is preferably a neutral paper having a pH of not more than 01% and a pH of 6.5 to 7.5. Further, the neutral paper preferably has a thickness of 20 to 30 g / m 2 so as not to be bulky when used, and to have a certain strength as a slip sheet.
Furthermore, it is preferable that the neutral paper is a neutral paper that has been polished on one or both sides by a super calender so as not to generate paper dust and damage the metal product surface. In this case, if the polishing process is performed only on one side, the air permeability remains in the slip sheet, and the moisture on the metal product surface is removed. As such a neutral paper, for example, "Toshishi Paper" (manufactured by Daiko Paper Co., Ltd.) (2)
Neutral paper such as 7 g / m 2 ) can be used.
