Protective plastic films are essential in meat preservation because they act as a barrier that helps maintain product safety and quality by controlling the immediate environment of the food.12

These films provide several key benefits:

  • Contamination Control: Covering meat with plastic films helps prevent microbial contamination, which is critical for extending shelf life.2
  • Moisture Retention: These materials prevent excessive moisture loss, which helps maintain the quality of the meat.2
  • Gas and Oxidation Management: Through modified-atmosphere packaging, plastic films can be selected for their specific permeability to gases like oxygen and carbon dioxide. By minimizing oxygen exposure, these films slow the oxidation of fatty acids, which prevents the development of rancidity.13
  • Vacuum Packaging: Many meat products are specifically vacuum-packaged using plastic films to remove oxygen, which inhibits the growth of aerobic bacteria and can extend refrigerated storage life to approximately 100 days.3
