Antimicrobial packaging is one of the many applications of active packaging. It is the packaging system which can stop or inhibit spoilage and pathogenic microorganisms contaminating foods. Antimicrobial function can be accomplished by adding antimicrobial agents in the packaging system or using antimicrobial polymers that answer conventional packaging requirements. When the packaging system gains antimicrobial activity, the packaging system or material limits or stops microbial growth by extending the lag period and decreasing the growth rate or live counts of microorganisms.
