A construction includes a substrate incorporating an activatable antimicrobial composition. The substrate includes a laminate having at least two layers bonded together by a thermoplastic bonding medium. The antimicrobial composition includes a peroxygen donor and an acid and/or an acid-producing substance. The peroxygen donor is incorporated separately and in a different portion of the substrate from the other component or components of the antimicrobial composition. Preferably, the antimicrobial composition includes a peroxygen donor in the form of sodium perborate as a mono or tetra hydrate, or sodium percarbonate and an acid-producing substance in the form of tetra acetyl ethylene diamine. Such an antimicrobial composition can be activated by wetting the substrate with water.
