Thus, we haveprepared a new fully organic and metal-free antimicrobial polymer, with the aim of increasing both the shelf lifeand safety of packaged meat. This antimicrobial polymer is based on widely available commercial acrylicmonomers with covalently linked vanillin motifs, which are naturally occurring essential oils with antimicrobialcharacteristics. The film-shaped antibacterial polymeric material shows antibacterial activity for Escherichia coli,Staphylococcus aureus, and Listeria monocytogenes with an R parameter of up to 3.18, 3.37 and 2.00 and inhibition% of up to 99.95%, 99.96%, and 99.02%, respectively. To show the potential of these materials, we conducted aproof of concept experiment in which the antimicrobial polymer film was used as an absorbent food pad. Theresults show that the use of the antimicrobial polymer film can increase the shelf life of a packaged meat productby 50%. Since the antimicrobial activity is based on a covalently anchored group, there is no antimicrobial agentdiffusion, and the antimicrobial activity persists beyond the first use because it is easily washable and reusablefor at least 10 cycles.
