Patent ID: 7922861

Claim:
A process for increasing the strength of a component of a laminated absorbent article, the process comprising increasing the material basis weight of the component by introducing a material basis weight increasing agent onto at least a portion of the component to increase the material basis weight of the treated portion of the component by at least about 10%, the material basis weight increasing agent comprising an atactic polymer and an isotactic polymer, the atactic polymer having a degree of crystallinity of less than about 20% and a number-average molecular weight of from about 1,000 to about 300,000, the atactic polymer being selected from the group consisting of atactic polystyrene, atactic polybutene, and combinations thereof, and the isotactic polymer having a degree of crystallinity of at least about 40% and a number-average molecular weight of from about 3,000 to about 200,000.
