Abstract

A multi-layer film for reducing microbial contamination on a surface. The multi-layer film can include a core layer having a first surface and a second surface opposite the first surface, an adhesive layer disposed adjacent the first surface of the core layer, and an antimicrobial layer disposed adjacent the second surface. The antimicrobial layer can include a cross-linked matrix and an antimicrobial agent dispersed within the cross-linked matrix, where the cross-linked matrix is derived from a polymerizable precursor comprising a material selected from the group consisting of a polymerizable monomer, a polymerizable polymer having a molecular weight of about 1,000 or less, and combinations thereof.
