Abstract
This invention relates to antimicrobial composites, films, labelstocks and labels. The antimicrobial composites comprise (A) a polymer mixture comprising a mixture of at least one styrene polymer and at least one urethane polymer, and (B) an antimicrobial composition which comprises at least one metal chlorite and at least one hydrophilic material capable of reacting with the metal chlorite when exposed to water. The composites which are described herein are useful in preparing films, labelstocks and labels which exhibit the desirable antimicrobial properties by providing a controlled release of chlorine dioxide gas over an extended period of time.
