Japan developed a shell film that can replace cellophane

The crustacean film that can be used instead of cellophane developed in Japan has a wide range of applications and can be used in packaging and decoration. The raw materials used to produce shell films are very rich. In nature, a considerable portion of insect shells or crustacean shells are made of chitin. Its main chemical composition is cellulose, which is the main raw material for the production of shell films.
The process of processing chitin shells with chitin is not complicated: First, the chitin is soaked with hydrochloric acid, and then calcium and protein are precipitated with strong alkali to obtain semi-finished shell powder. Then the carapace powder was dissolved in a mixture of dimethylamine acetate, amphetamine and potassium chloride. The wine was evenly spread on a glass plate and immersed in a solution of isopropyl alcohol to form a transparent glass plate. Shellfish film.
