Abstract: A heat-shrinkable anti-fomitic device incorporating anti-microbial metal wherein the device, in the form of a bag or tube, forms a cover for an object, preventing cross-infection by bacteria and other pathogens that may reside on the object. Anti-microbial metal ions from the cover further reduce future cross-infection from the object by killing pathogens. The anti-microbial, heat-shrinkable, anti-fomitic device can have a sterile interior that is sealed or stored flat during manufacture to maintain sterility. Therefore, no outer wrapping for the anti-fomitic device is required. The anti-fomitic device can be inverted when used to cover the object to present an outer surface that is initially sterile. A plurality of such devices can be heat shrunk to an object such that removal of the outer layer will further prevent cross contamination. Heat shrink film materials for the coverings/bags serve as a barrier to the transmission of pathogens and conform closely to the covered object.
