...the adhesive has everything to do with this. If the adhesive was stronger, the curling would not have enough force to lift it off the wall. Post-its only exist because of their weak adhesive...and it's because their adhesive is weak that curling is an issue for them. edit: by which I mean...if the adhesive was stronger, the post-its could curl and still stick to the wall. Post-its' soft adhesive lets them easily peel from each other, but also lets the minor force of a curled post-it unstick it from the wall. |
