Fighting slime: Researchers develop bacteria-killing plastic film
Plastic films made with bacteria-killing polymers have been proven effective as a frontline defense — not to mention offense — in the battle against biofilms in food production operations.
A preferred place of residence for pathogens such as Listeria and E. coli, biofilms form easily and are extremely difficult to eradicate, according to the Food and Drug Administration, the Centers for Disease Control and Prevention and the U.S. Department of Agriculture.
Biofilms are aggregates of bacteria that highly increase bacterial resistance to antimicrobials, as well as to disinfectants, according to the American Society of Microbiology.
But, by modifying the polymer matrix of plastic films, researchers have developed a rechargeable disinfecting material that can be applied to conveyor belts, food-contact surfaces, utensils and other equipment and surfaces.
