LAMINATE OF SHEET OF HYGIENIC THIN PAPER, CARTON, AND MANUFACTURING METHOD FOR LAMINATE OF SHEET OF HYGIENIC THIN PAPER

摘要

PROBLEM TO BE SOLVED: To provide a laminate of sheets of hygienic thin paper, the laminate being able to be securely reduced in height and able to prevent the height of the laminate from changing according to seasons.SOLUTION: In a laminate of hygienic thin paper, the horizontal tensile strength per pair of sheets of hygienic thin paper when it is dried is expressed by DCDT (N/25 mm), the vertical tensile strength per pair of sheets hygienic thin paper when it is wet is express by WMDT (N/25 mm), and the density of it is expressed by D (g/cm). The laminate is manufactured by folding sheets of hygienic thin paper and subjecting it to a compression process in the direction of lamination with a pull unit. The bulk recovery rate of the laminate, expressed by (the height t of a laminate after the compression process)/(the height tx of the laminate before the compression process) is 80% or less. The compression rate expressed by (pull unit gap G)/(tx) is 30 to 50%. The height H (mm) of the laminate after the compression process is expressed by N×0.1×α×BW≤H≤N×0.11×α×BW relative to the number of sheets (N) of hygienic thin paper and the basis weight per sheet (BW (g/m)).
