Abstract
A stretch laminate having a first substrate is adhesively attached to an elastic film. The adhesive is applied in a continuous manner to the substrate in a first tack down region which is disposed proximate to an end of the stretch laminate. The adhesive is applied as a plurality of adhesive stripes in an activation region which is interior of the first tack down region. The adhesive stripes have a width and a distance between adjacent adhesive stripes. The ratio of stripe width to distance between the adhesive stripes is in the range of less than about 1 or greater than about 0.33.
Claims17
A mechanically activated stretch laminate comprising:
- a first substrate;
- an elastic film attached to the first substrate via an adhesive such that the first substrate is attached to the elastic film on a face of the film;
- at least one tack down region disposed proximate to an end of the stretch laminate;
- and
- an activation region disposed interior of the tack down region;
- wherein the adhesive in the activation region includes a plurality of stripes having a distance between adjacent stripes and each stripe having a stripe width, wherein a ratio of the stripe width to the distance between adjacent stripes is from about 0.33 to about 0.5;
- and
- wherein the adhesive in the tack down regions has a different basis weight than adhesive in the activation region.
A mechanically activated stretch laminate comprising:
- a first substrate;
- an elastic film attached to the first substrate via an adhesive such that the first substrate is attached to the elastic film on a face of the film;
- at least one tack down region disposed proximate to an end of the stretch laminate;
- and
- an activation region disposed interior of the tack down region;
- wherein the adhesive in a portion of the intermediate region includes a plurality of stripes having a width of less than 1 mm, the distance between adjacent stripes being 1.5 mm;
- wherein the Peel Force value of the first substrate and the elastic film is between about 119 g/cm and about 271 g/cm;
- and
- wherein the adhesive in the tack down regions has a different basis weight than adhesive in the activation region.
