Abstract
Provided is an absorbent article including an absorbent layer and a top sheet having a number of perforations and disposed on a body facing surface of the absorbent layer. The top sheet is made of a multi-layered resin film having at least two resin layers composing of an outer resin layer exposed outside the body facing surface and at least one inner resin layer disposed nearer to the absorbent layer than the outer resin layer thereto. At least, the outer resin layer contains a particulate material having a mean particle size of from 2 μm to 20 μm, and the inner resin layer has the resin density smaller than that of the outer resin layer.
Claims12
An absorbent article comprising:
- an absorbent layer;
- and
- a top sheet having a number of perforations and disposed on a body facing surface of the absorbent layer,
- the top sheet being made of a multi-layered resin film having at least two resin layers consisting of an outer resin layer located at a distal side of the top sheet relative to the body facing surface and at least one inner resin layer located at a proximal side of the top sheet relative to the body facing surface of the absorbent layer, at least the outer resin layer containing a particulate material having a mean particle size of from 2 μm to 20 μm for attaining a predetermined stiffness necessary for ensuring a comfortable fit, and the inner resin layer having the resin density smaller than that of the outer resin layer for attaining a level of flexibility necessary for providing flexibility for the top sheet.
An absorbent article comprising:
- an absorbent layer;
- and
- a top sheet having a number of perforations and disposed on a body facing surface of said absorbent layer, said top sheet being made of a multi-layered resin film having at least two resin layers consisting of an outer resin layer made of thermoplastic resin and located at a distal side of said top sheet relative to said body facing surface and at least one inner resin layer made of a thermoplastic resin that identical to said outer resin layer and located at a proximal side of said top sheet relative to said body facing surface of said absorbent layer, at least said outer resin layer containing a particulate material having a mean particle size of from 2 μm to 20 μm for attaining a predetermined stiffness necessary for ensuring a comfortable fit, and said inner resin layer having a resin density which is smaller than that of said outer resin layer for attaining a level of flexibility necessary for providing flexibility for said top sheet.
An absorbent article comprising:
- an absorbent layer;
- and
- a top sheet having a number of perforations and disposed on a body facing surface of said absorbent layer, said top sheet being made of a multi-layered resin film having at least two resin layers consisting an outer resin layer located at a distal side of said top sheet relative to said body facing surface and at least one inner resin layer located at a proximal side of said top sheet relative to said body facing surface of said absorbent layer, at least said outer resin layer containing a particulate material having a mean particle size of from 2 μm to 20 μm for attaining a predetermined stiffness necessary for ensuring a comfortable fit, said outer resin layer containing from 30 to 60 parts by weight, relative to 100 parts by weight of a resin that forms said outer resin layer, of the particulate material, and said inner resin layer having a resin density which is smaller than that of the outer resin layer for attaining a level of flexibility necessary for providing flexibility for said top sheet.
