ABSORBENT ARTICLES WITH NON-ADHERENT MEMBER
Example absorbent articles including a non-adherent member comprising a polyester, a substrate adjacent the non-adherent member, and an absorbent member disposed between the non-adherent member and the substrate are disclosed. The non-adherent member defines a plurality of perforations extending through a thickness of the non-adherent member. Example techniques for forming example articles are disclosed.
1 . An absorbent article comprising:
a non-adherent member comprising a polyester, wherein the non-adherent member defines a plurality of perforations extending through a thickness of the non-adherent member;
a substrate adjacent the non-adherent member; and
an absorbent member disposed between the non-adherent member and the substrate.
2 . The absorbent article of claim 1 , wherein the non-adherent member is configured to non-adheringly contact skin of a patient.
3 . The absorbent article of claim 1 , wherein the non-adherent member comprises a polymeric film.
4 . The absorbent article of claim 3 , wherein the polymeric film consists essentially of the polyester.
5 . The absorbent article of claim 1 , wherein the polyester comprises polyethylene terephthalate.
6 . The absorbent article of claim 1 , wherein the absorbent member comprises a superabsorbent material.
7 . The absorbent article of claim 6 , wherein the substrate is moisture vapor permeable.
8 . The absorbent article of claim 7 , wherein the substrate has a moisture vapor transmission rate of at least about 500 grams per meters squared per day.
9 . The absorbent article of claim 8 , wherein the substrate comprises a laminated member.
10 . The absorbent article of claim 9 , wherein the laminated member comprises a nonwoven layer and a supporting film.
11 . A wound dressing comprising the absorbent article of claim 1 .
12 . A method of forming an absorbent article, the method comprising:
securing an absorbent member to a substrate; and
securing at least a portion of a non-adherent member comprising a polyester to at least a portion of the absorbent member, wherein the non-adherent member defines a plurality of perforations extending through a thickness of the non-adherent member.
13 . The method of claim 12 , further comprising securing at least another portion of the non-adherent member to at least a portion of the substrate.
14 . The method of claim 12 , wherein one or both of the securing the absorbent member or securing at least a portion of the non-adherent member comprises one or more of heat bonding, adhesive bonding, static bonding, or corona treatment.
15 . The method of claim 12 , wherein the non-adherent member comprises a polymeric film.
16 . The method of claim 15 , wherein the polymeric film consists essentially of the polyester.
17 . The method of claim 12 , wherein the polyester comprises polyethylene terephthalate.
18 . The method of claim 12 , wherein the substrate has a moisture vapor transmission rate of at least about 500 grams per meters squared per day.
19 . The method of claim 12 , wherein the absorbent member comprises a superabsorbent material.
20 . The method of claim 12 , further comprising laminating a nonwoven layer to a supporting film to form the substrate.
