- Example 5 in which the repeating structural unit derived from DCP in the norbornene-based polymer was less than 40% by weight, the heat resistance, the heat sealing property, and the moisture permeability were slightly different among the examples. The evaluation was low. Further, Oite thickness of the resin layer is extremely thin in Example 7 and 3 ⁇ M is heat resistance and moisture permeability, whereas c becomes slightly evaluation is low results in the examples, of the norbornene-based polymer Comparative Example 1 in which the blending ratio is smaller than the specified ratio has poor heat resistance and slightly poor moisture permeability. In addition, the blending ratio of the norbornene-based polymer was higher than the specified value. In Comparative Example 2, heat sealability was poor, resulting in a result.
