Since the resin contains a crosslinking agent and a crosslinking aid, it is necessary to suppress the crosslinking reaction when the resin is formed into a sheet. For this reason, the molding temperature cannot be raised sufficiently, and a lot of distortion remains in the sealing sheet during sheet molding. Therefore, the sheet contracts greatly by heating during vacuum lamination. Particularly in recent years, there is a tendency to lower the crosslinking temperature in order to shorten the processing time of the vacuum laminating process.
