Tasked by Johnson & Johnson to re-imagine pantiliners for young women, and to find a way to make them more appealing for everyday use, the Stretch Liner was developed.

In group research of women young and old, the top complaints of pantiliner function were fear of visibility during intimate moments, and the bunching and shifting that occurs while in use.

In research and testing, we found that the surface area required for function was actually much smaller than current liner sizes, and that this added bulk was largely to provide a large enough surface area for adhesion.

My innovation attempts to reduce the bulk by combatting the stretching forces that necessitate the current amount of adhesive to keep the liner in place. To this end, I developed a liner built off of a sheer bi-axial stretch fabric, which allows the liner to stretch and deform with the user’s movements, and reduces the absorbent pad to a less noticeable size while still remaining perfectly functional.

The design relies on a heat-set material, which is bonded to the stretchable mesh to prevent adhesive from seeping through and sticking to the skin.

Wrapped: Back View

Step 1
The adhesive rear backing is removed.

Step 2
The protective front backing is removed.

Step 3
Support backing remains to aid application.

Step 4
The liner can now be placed in the underwear, with the transparent mesh allowing for easy alignment.

With the liner now in place, the support backing which held its shape during application process can now be removed.

Once in place, the liner will move and stretch with the user, avoiding any bunching or noticeable presence.
