Abstract
Methods and (articles of manufacture therefrom) including forming an elastic film from a polymer composition; tensioning the elastic film to a stretch ratio of between 2 and 6 in the MD; laminating the elastic film to an extensible facing to provide an elastomeric laminate having a CD hysteresis loss of 70% or less and an MD hysteresis loss of 50% or less.
Claims21
A method comprising:
- forming an elastic film from a polymer composition;
- tensioning the elastic film to a stretch ratio of between 2 and 6 in the MD;
- laminating the elastic film to an extensible facing, to provide an elastomeric laminate having a CD hysteresis loss of 70% or less and an MD hysteresis loss of 50% or less, and/or a 45 MDCD of less than 2.05 cm.
An elastomeric laminate comprising:
- an elastic film;
- an extensible facing laminated to the elastic film;
- and
- wherein the elastomeric laminate has a CD hysteresis loss of 70% or less and an MD hysteresis loss of 50% or less, and/or wherein the elastomeric laminate has a 45 MDCD of less than 2.05 cm.
