SURFACE MATERIAL OF ABSORBENT ARTICLE AND MANUFACTURE OF THE SAME

Japanese Patent JP3260863

B2

PURPOSE: To try to prevent longitudinal tearing, to reduce elongation and to maintain liquid permeability and other properties for preventing liquid return, fitting, and shielding of a surface material of an absorbent article by forming the material with a resin composition in which a specified amount of polypropylene is blended to 100 pts.wt. of low density polyethylene or linear low density polyethylene.
CONSTITUTION: A surface material comprises a liquid-inpermeable material covering the surface of an absorbent 3 of an absorbent article 1 and has a number of pore parts 4 in which an opening for liquid permeation is formed. The surface material comprises a resin composition in which 1-50 pts.wt. of polypropylene is blended to 100 pts.wt. of low density polyethylene or linear low density polyethylene. When the amount of polypropylene is less than 1 pts.wt., the improvement in tear strength and tensile strength is inadequate, and when the amount exceeds 50 pts.wt., the touch of the surface material is deteriorated in spite of the improvement in strength. This is the reason for the restriction of the composition.
