Sealants and packaging materials used for transport packaging of silicone materials, shipping packaging of silicone materials, and packaging of silicone materials

摘要

PROBLEM TO BE SOLVED: To provide a sealant, a packaging material, a silicon wafer transportation package and a silicon wafer package used for a silicon wafer transportation package having a predetermined transparency and a predetermined slipperiness. A sealant used for a packaging for transporting a silicon wafer has a first surface and a second surface facing the first surface, and the Kurtosis Rku of the first surface is 20 or less and the first surface. The arithmetic mean roughness Ra of the above is 0.04 μm to 0.10 μm. [Selection diagram] Fig. 1
