  • They dissolve in water in 24 hours, and could be used to pack fruit, vegetables, poultry, meat, and seafood.
  • Researchers created 3 types of food films based on sodium alginate, a natural biopolymer from seaweeds.
  • Sodium alginate is mixed with a natural acid that makes the films strong, and has antioxidant components that can prolong food’s shelf life.
  • It’s possible to enrich the films with natural antiviral substances like garlic, turmeric or ginger in order to extend food’s life even more.
  • Making these films requires no special equipment, it could be made in food or film factories.
