Food packaging, as an important means of protecting food and extending shelf life, the safety of its materials directly affects the health of consumers. White carbon black, as a non-toxic and odorless inorganic material, has demonstrated unique safety advantages in the field of food packaging.



Barrier performance improvement: White carbon black can be added to plastic films to form micro nano structures, significantly improving the barrier performance of the film, effectively preventing external factors such as oxygen and moisture from damaging food, and extending the shelf life of food.


Enhanced antibacterial performance: Through special treatment, white carbon black can endow packaging materials with antibacterial properties, inhibit the growth of bacteria, mold and other microorganisms, and ensure the safety and hygiene of food.


Environmentally friendly and biodegradable: With the increasing awareness of environmental protection, biodegradable food packaging materials have become a research hotspot. White carbon black, as a natural inorganic filler, can be combined with biobased materials to prepare environmentally friendly and biodegradable food packaging materials, reducing plastic pollution.


The safe application of white carbon black in food packaging not only improves the performance of packaging materials, but also meets consumers' needs for food safety and environmental protection, which is an important direction for the future development of the food packaging industry.
