摘要： The object of the present invention is to provide a base sheet for a total heat exchanger element such that the base sheet has a high moisture permeability and an appropriate rate of moisture absorption as well as excels in flame resistance and gas barrier properties while its basis weight is low. A base sheet for a total heat exchanger element comprising calcium chloride in a paper base material, characterized in that the paper base material comprises pulp with a freeness of from 200 to 600 ml as measured in accordance with JIS P 8121 except that a pulp collection amount is set to 0.3 g/L; the paper base material has a bone-dry basis weight of from 17 g/m2 to less than 23 g/m2; and content of the calcium chloride is from 6 g/m2 to less than 9 g/m2.

摘要： Provided is a glass interleaving paper capable of suppressing scratches on surfaces of glass plates in a manufacturing process or a distribution process for storing and transporting a plurality of stacked glass plates. The glass interleaving paper is characterized in that a main component is cellulose pulp, a basis weight is 10 to 100 g/m2, and content of mineral having a Mohs hardness of at least 5 is 400 ppm or less. When the mineral having a Mohs hardness of at least 5 is a silicate mineral, the glass interleaving paper is more useful.

摘要： Provided is a glass plate interleaving paper including cellulose pulp as a main component. A percentage of aluminum content is below 0.2 mass %, and a basis weight is in a range from 10 to 100 g/m2. Further, it is preferred that the glass plate interleaving paper have a percentage of aluminum content below 0.01 mass %. Still further, it is preferred that the glass plate interleaving paper have a percentage of talc content below 0.1 mass %.
