Packaging and Technology

With the economic development and improvement of people's living standards, the packaging of goods is particularly important. The development of edible packaging in the foreign packaging industry mainly focuses on materials selection, processes, etc. All kinds of popular packaging technologies have become the preferred development research topic.
1. Chitosan Edible Packaging Film: This packaging film uses shellfish extract chitosan as the main raw material, combining chitosan with lauric acid to produce a uniform edible film. The peeled fruit and fruit pieces are well preserved with the packaging film.
2. Corn protein packaging film: This packaging film is mainly used for fast food boxes and other oil food packaging coatings. The film is a packaging material for the synthesis of paper and corn protein. It is not penetrated by oils and fats. It is put into a pot and boiled without changing its properties.
3. Soy Protein Edible Packaging Film: This packaging film not only prevents oxygen from entering, but also maintains moisture while ensuring the original flavor of the food.
4. Composite Edible Packaging Film: This protein, fatty acid, and starch composite edible packaging film is an edible film that combines different ratios of protein, fatty acid and starch to produce different physical properties.
5. Corn starch, sodium alginate or chitosan composite packaging film: The composite packaging film is based on corn starch, sodium alginate or chitosan is added, and plasticizer, thickener and preservative are added, and the special process is adopted. Processed.
6. Water-resistant protein film: This is a new type of packaging material that can replace foamed ethylene. Because its main ingredient is corn, it has biodegradability and will not pollute the environment.
7. Edible wrapper made from bean dregs as raw material: This kind of wrapper is suitable for packaging of fast food noodles seasoning. It can be melted with hot water and has nutritional value.
8. Protein-coated wrapper: This novel wrapper is non-toxic, easy to handle, and can withstand a certain temperature and moisture attack. The wrapper or container is a thin-film wrapper made by dissolving the shellac or protein and special process. Or packaging containers.
