This packaging film can eat, there are a variety of tastes! 500 times higher barrier property

Scientists in the United States are developing a packaging film called cow's milk protein called casein. According to reports, the micropores in the film materials made from cow's milk protein are smaller than the micropores in the existing plastic packaging film materials, and are blocked. In terms of oxygen capacity, this casein film material is more than 500 times better than existing packaging plastic film materials.

In addition to improving the preservation of packaging materials, this material can also reduce the environmental pollution of packaging materials, because it is biodegradable. After eating the packaged food, it can even eat a piece of packaging material, but it tastes itself. There is no taste, but new flavors can be added constantly. Vitamins, probiotics and other nutrients can also be added to make it more nutritious.

In addition, during the course of the study, the researchers discovered that if the film material prepared using this bovine milk cheese protein has disadvantages such as poor softness and being particularly soluble in water, the researchers modified it by adding citrus pectin to make the material. Tougher, and improved heat resistance and moisture resistance.

Once the new packaging film enters the market on a large scale, the benefits are obvious. At present, a company in Texas, USA, has begun trialing this casein film for food packaging and is expected to start mass production within the next three years.
