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. ## Claims ### Claim 1 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. ### Claim 2 (depends on 1) The mechanically activated stretch laminate of claim 1 further comprising a second substrate adhesively attached to an opposite face of the elastic film from the first substrate such that the elastic film is sandwiched between the first and second substrate. ### Claim 3 (depends on 1) The mechanically activated stretch laminate of claim 1, wherein the at least one tack down region includes a first tack down region disposed proximate to an end of the stretch laminate and a second tack down region disposed proximate to another end of the stretch laminate, wherein adhesive in the first and second tack down regions includes a continuous layer, and wherein the activation region is disposed between the first tack down region and the second tack down region. ### Claim 4 (depends on 1) The mechanically activated stretch laminate of claim 1, wherein the adhesive stripes are continuous. ### Claim 5 (depends on 1) The mechanically activated stretch laminate of claim 1, wherein at least some of the adhesive stripes comprise a plurality of discrete elements. ### Claim 6 (depends on 1) The mechanically activated stretch laminate of claim 1, wherein adhesive stripes in a portion of the activation region have a basis weight of 6 gsm while adhesive stripes in another portion of the activation region have a basis weight of 8 gsm. ### Claim 7 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. ### Claim 8 (depends on 7) The mechanically activated stretch laminate of claim 7 further comprising a second substrate adhesively attached to an opposite face of the elastic film from the first substrate such that the elastic film is sandwiched between the first and second substrate, and the Peel Force value of the second substrate and the elastic film is between about 63 g/cm and about 128 g/cm. ### Claim 9 (depends on 7) The mechanically activated stretch laminate of claim 7, wherein the at least one tack down region includes a first tack down region disposed proximate to an end of the stretch laminate and a second tack down region disposed proximate to another end of the stretch laminate, wherein adhesive in the first and second tack down regions includes a continuous layer, and wherein the activation region is disposed between the first tack down region and the second tack down region. ### Claim 10 (depends on 7) The mechanically activated stretch laminate of claim 7, wherein the adhesive stripes are continuous. ### Claim 11 (depends on 7) The mechanically activated stretch laminate of claim 7, wherein at least some of the adhesive stripes comprise a plurality of discrete elements. ### Claim 12 (depends on 7) The mechanically activated stretch laminate of claim 7, wherein adhesive stripes in a portion of the activation region have a basis weight of 6 gsm while adhesive stripes in another portion of the activation region have a basis weight of 8 gsm. ### Claim 13 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 2 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. ### Claim 14 (depends on 13) The mechanically activated stretch laminate of claim 13 further comprising a second substrate adhesively attached to an opposite face of the elastic film from the first substrate such that the elastic film is sandwiched between the first and second substrate, and the Peel Force value of the second substrate and the elastic film is between about 63 g/cm and about 128 g/cm. ### Claim 15 (depends on 13) The mechanically activated stretch laminate of claim 13, wherein the adhesive stripes are continuous. ### Claim 16 (depends on 13) The mechanically activated stretch laminate of claim 13, wherein at least some of the adhesive stripes comprise a plurality of discrete elements. ### Claim 17 (depends on 13) The mechanically activated stretch laminate of claim 13, wherein adhesive stripes in a portion of the activation region have a basis weight of 6 gsm while adhesive stripes in another portion of the activation region have a basis weight of 8 gsm.
