  • the degree of MCT diffusion was not so different between the base paper and the laminate 1, but the degree of diffusion was lower in the laminate 2 having the oil resistant layer than in these samples. Do you get it. It is considered that this is because the sample diffusion was suppressed by the oil resistant layer.
  • the opacity it was found from Table 3 above that the laminate 1 having no oil resistant layer but having a CaCO 3 containing layer had lower transparency than the base paper, and the laminate 2 having an oil resistant layer had an opacity. It turned out that the transparency can be maintained. It is considered that this is because the oil-resistant layer suppresses the penetration of the sample. Therefore, it was found that the laminated body 2 which is the chip paper according to the present embodiment can suppress the diffusion of MCT and further suppress the decrease in transparency.
