PURPOSE:To obtain adhesive paper prevented from curling even in a high or low humidity range, and from paper jamming during paper feed or conveyance by using specified paper as paper for use in an adhesive sheet and a strippable sheet. CONSTITUTION:A pulp material consisting of >=30% needle-leaved wood pulp and <=70% broad-leaved wood pulp is beat to >=350cc CSF, and additives, such as binder, e.g., melamine resin, and a filler, e.g., talc, are added to the pulp, the obtained slurry is adjusted in J/W ratio so as to render orientation of the pulp fibers random, and a slice is controlled to raise a ratio of longitudinal tensile strength to lateral one of a paper layer to >=75%. 2 kinds of paper thus made have <=1.5 and <=1.0 in elongation degree immersed in water, respectively. An adhesive layer is formed on one side of the paper higher in said degree to obtain an adhesive sheet, and a strippable layer is formed on one side of the paper lower in said degree to obtain a strippable sheet, and both coated faces are laminated to obtain adhesive paper. |
