Foreign packaging industry

With the economic development and improvement of people's living standards, the packaging of goods is particularly important. At present, the development of edible packaging in countries around the world mainly focuses on materials selection, processes and other aspects. The various popular technologies for packaging have become the preferred development research topic. The major hot technology development for foreign packaging is introduced as follows:
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 packaged with the packaging film, which has a good freshness preservation effect.
2. Corn protein packaging film: This packaging film is mainly used for fast food boxes and other oiled 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: The packaging film can not only prevent oxygen from entering, but also maintain moisture and ensure the original flavor of food.
4. Compound Edible Packaging Film: This protein, fatty acid, and starch compound edible packaging film is an edible film that combines different ratios of proteins, fatty acids, 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, adding sodium alginate or chitosan, together with plasticizers, tackifiers, and preservatives. Special processing process.
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: This wrapper is suitable for the packaging of instant noodles seasonings. 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 certain temperature and moisture erosion. The wrapper or container is made by dissolving the shellac or protein by a special process. Film wrapping or packaging containers.
