On the use of cellulose acetate film for food packaging
There is cellulose acetate film now, which is very good for food packaging. Cellulose acetate film has many wonders. First, its quality is soft, easy to pack, and can fit the shape of the food without damaging its appearance. Second, its moisture permeability and air permeability are moderate. With moderate moisture permeability, the food can be kept dry and will not get damp and mildew; with suitable air permeability, the food can be slow to breathe, preserve its freshness, and prolong its shelf life.

Furthermore, cellulose acetate film has good barrier properties. It can effectively block gases such as oxygen and carbon dioxide. Oxygen intrusion can cause food oxidation, color change, taste change, and nutrient loss. This film blocks oxygen, so that the food can be protected, and the color and flavor can be maintained for a long time. The escape or entry of carbon dioxide is related to the taste of the food, and the film can also control it, so that the bubbles of gas-containing foods such as soda are filled and the taste is good.

And its chemical stability is quite good. In contact with food, it does not chemically react with food ingredients, does not contaminate food, and ensures food safety. In the packaging process, cellulose acetate film is easy to process and form, or make bags, or wrap, which can be convenient and increase the efficiency of packaging.

Therefore, cellulose acetate film is very useful in the field of food packaging. It is a good material for food packaging, which can protect the quality of food, prolong the life of food, and benefit consumers.
