The use of self-healing polymer materials in the form of film or coating in the food packaging industry can be very promising, because in case of damage, they can automatically repair and restore the integrity of their surface and characteristics by themselves. Packages are usually inevitably and imperceptibly damaged during transportation, handling and storage. In this case, the damaged parts of common packages, which lack self-healing ability, become susceptible to microbial growth due to exposure to the environment. This may endanger the quality and safety of food products. Within the realm of food packaging research, self-healing films and coatings have been developed using both intrinsic and non-intrinsic mechanisms. The former involves non-automatic self-healing in the presence of an external stimulus, while the latter mechanism enables automatic self-repair. In this study, self-healing mechanisms and the associated films and
coatings have been explored and the feasibility and benefits of incorporating these materials into the realm of food packaging have been investigated. It should be mentioned that so far self-healing films and coatings have primarily been developed and examined mainly on a laboratory scale in order to conduct scientific studies. Moreover, recent review articles have rarely considered the real limitations of the industry in relation to improving the practical application of these films and coatings in the food packaging sector. Therefore, unlike previous studies, the present study has also examined the specific challenges of the industry in the field of self-healing packaging development and emphasized their importance.
