U.S. Scientist Develops Renewable and Degradable New Type of Milk Protein Packaging Material

[China Packaging Network News] Oxidation exposure is the main cause of food corruption. The Agricultural Research Service ( ARS ) of the U.S. Department of Agriculture recently released news that U.S. scientists developed a new type of food packaging film using milk protein such as casein. This packaging material is more effective than traditional food cling film in isolating air and maintaining food freshness. 500 times stronger performance .

The casein packaging developed by scientists at the Agricultural Research Service Dairy Functional Food Research Unit in Wyndmoor, Pa ., creates a new value-added market for US dairy products. The successful development of these materials has provided the market with a renewable, biodegradable alternative to food packaging that is more competitive than previous packaging films derived from petrochemical materials. This new film is more resistant to water and oil and can be used directly in the packaging of cheese sticks, baked goods and confectionery.
