Title:
LAMINATE SHEET, PRODUCTION METHOD OF LAMINATE SHEET AND DEVICE OF LAMINATE SHEET
Document Type and Number:
Japanese Patent JP2019115667
Kind Code:
A
Abstract:
To provide a laminate sheet comprising a function with high added value and improving a performance significantly, relative to prior ones.SOLUTION: A laminate sheet comprises: crepe sheets as a pair of outer sheets; and a nonwoven fabric as a heat-seal intermediate layer sheet provided between the pair of crepe sheets in a laminated state, the crepe sheets are heat-sealed to the intermediate layer sheet by a linear heat-seal part row extending in a direction orthogonal to an extension direction of crepe wrinkles on the crepe sheets, for forming a laminate structure. A crepe ratio of the crepe sheet is 20-30%, and an interval between the heat-seal parts in a width direction of the heat-seal part row is 10-25 mm. In a range of the interval between the heat-seal parts in the width direction, an interval of heat-seal parts in the width direction is increased in proportional to increase of the crepe ratio of the crepe sheet.SELECTED DRAWING: Figure 1
