Abstract

An absorbent article is disclosed having a topsheet, a backsheet joined with the topsheet, an absorbent core disposed between the topsheet and the backsheet, and a synthetic superabsorbent polymer derived from a first renewable resource via at least one intermediate compound, wherein said superabsorbent polymer exhibits a defined Saline Flow Conductivity value and Absorption Against Pressure value. Alternately, an absorbent article is disclosed having a synthetic polyolefin derived from a first renewable resource via at least one intermediate compound. The synthetic polyolefin exhibits defined performance characteristics making the polyolefin particularly useful in certain components of the absorbent article. Methods for making the aforementioned absorbent articles are also disclosed.

Claims

exact text as granted — not AI-modified
1 - 20 . (canceled) 
     
     
         21 . A backsheet film of an absorbent article, the backsheet film is at least partially formed from a polymer and exhibits a  14 C/C ratio of about 1.0×10 −14  or greater, wherein the polymer is at least partially derived from a renewable resource via at least one intermediate compound, the polymer is synthetic, the intermediate compound is monomeric, the polymer is a polyolefin, the backsheet film is breathable and exhibits a Moisture Vapor Transmission Rate from about 2000 g/m 2 /hr to about 3000 g/m 2 /hr and an MD tensile strength from about 0.5 N/cm to about 6 N/cm. 
     
     
         22 . The backsheet film of  claim 21  having a thickness of about 0.5 mil to about 2.0 mils. 
     
     
         23 . The backsheet film of  claim 21  exhibits a  14 C/C ratio of about 1.0×10 −13  or greater. 
     
     
         24 . The backsheet film of  claim 23  exhibits a  14 C/C ratio of about 1.0×10 −12  or greater. 
     
     
         25 . An absorbent article comprising the backsheet film of  claim 21 . 
     
     
         26 . A package comprising one or more absorbent articles according to  claim 25 , wherein the package comprises a communication of a related environmental message to a consumer.
