Food security is very important in all processes executed for the manufacture of meat in meatpacking industries. Meat security can be improved by the use of accessories produced with antimicrobial materials in the manufacture lines. In this work, the antibacterial property was incorporated in the plates of polyamide 6 by the addition of two antibacterial compounds and the antimicrobial characteristics were studied. The antibacterial materials used were glass microparticles doped with ionic zinc and zinc oxide nanoparticles. The antibacterial polyamide 6 was produced containing different percentages of antibacterial compound and its microbiological characterization was realized with the bacteria Salmonella typhimurium and Staphylococcus aureus . The distribution of the antimicrobial compound in polyamide 6 matrix was evaluated by scanning electron microscopy and energy dispersive spectroscopy. Atomic absorption spectrometry was applied to study the migration capacity of the antibacterial compound in the aqueous medium. The results demonstrated that the polyamide 6 containing glass microparticles doped with ionic zinc present better antibacterial action than the polyamide 6 containing zinc oxide nanoparticles. © 2017 Wiley Periodicals, Inc.
