  • Patent number: 7910171
    Abstract: An antibiotic film comprised of a base adhesive layer of Ethylene Vinyl Acetate (EVA), a second layer of Polyethylene Terephthalate (PET), and a final layer of an antibiotic, preferably a zeolite contained in a water-based acrylic coating. The antibiotic laminating film is formed by passing a base film layer with water based zeolite and acrylic dispersion coated thereon through an oven to remove all water from the dispersion. The film is then wound into a roll until it is ready for extrusion coating with a thermal adhesive. After extrusion coating, the plain side of the film is corona treated and primed to promote adhesion. The thermal adhesive is then extruded onto the primer side of the film layer and cooled. The adhesive side of the film is then cooled.
