Abstract
Antimicrobial films are disclosed herein. The antimicrobial films are configured for application to surfaces, particularly to surfaces with which humans and animals come into contact. The antimicrobial films include a substrate layer and an antimicrobial layer. The substrate layer is generally a polymer, such as polyethylene. The antimicrobial layer is generally a composition of an antimicrobially-active ingredient dispersed in a dispersant. Typical dispersants include aqueous-based or solvent-based components (e.g., inks, primers, or varnishes). Antimicrobial films, as described herein, may be affixed to surfaces using an adhesive. Alternatively, the antimicrobial films may be applied to a surface using a heat-shrink process.
Claims23
An antimicrobial film, comprising:
- a polymer film substrate;
- an antimicrobial coating disposed as a layer upon a first surface of the substrate and a second surface of the substrate, the antimicrobial coating comprising an antimicrobially-active ingredient and a dispersant, wherein the first surface and the second surface are on opposite sides of the substrate;
- and
- an adhesive disposed upon the second surface of the substrate.
A method of making an antimicrobial film, the method comprising:
- dispersing an antimicrobially-active ingredient in a dispersant to form a mixture,
- printing a coating of the mixture upon a first surface and a second surface of a substrate as a layer using a printing technique, wherein the substrate comprises a polymer film, wherein the first surface and the second surface are on opposite sides of the substrate;
- and
- disposing an adhesive upon the second surface of the substrate.
A method of preventing microbial growth and accumulation on a surface, the method comprising:
- applying an antimicrobial film to the surface, wherein the antimicrobial film comprises:
- a polymer film substrate, and
- an antimicrobial coating disposed as a layer upon a first surface of the substrate and a second surface of the substrate, the antimicrobial coating comprising an antimicrobially-active ingredient and a dispersant, wherein the first surface and the second surface are on opposite sides of the substrate, and
- an adhesive disposed upon the second surface of the substrate.
An antimicrobial tape film, comprising:
- a polymer film substrate;
- an antimicrobial coating disposed as a layer upon a first surface of the substrate and a second surface of the substrate, the antimicrobial coating comprising an antimicrobially-active ingredient and a dispersant;
- adhesive disposed on the second surface of the substrate;
- and
- a release liner in contact with the adhesive, wherein the first surface and the second surface are on opposite sides of the substrate.
