Abstract
An antimicrobial-impregnated adhesive sheet includes an antimicrobial and a pressure-sensitive adhesive. The sheet includes a first major surface and a second major surface. The sheet includes a plurality of surface depressions extending inwardly from the first major surface. An initial available fraction of antimicrobial at the first major surface is at least 30%, based on the total amount of antimicrobial in the antimicrobial-impregnated adhesive sheet. The sheet exhibits a retention of the initial available fraction of antimicrobial at the first major surface, after accelerated aging, of at least 50%.
