What is EVOH?
Ethylene vinyl alcohol copolymer (EVOH) is a crystalline polymer with a chain-like molecular structure.
EVOH exhibits excellent barrier properties, processability, transparency, elasticity, crystallinity, and weather resistance. The resin is halogen-free, making it environmentally friendly, and its waste can be recycled. Its gas barrier properties are particularly outstanding, making it widely used in various packaging materials.
Application
-Food packaging:
China’s EVOH consumption is mainly concentrated in the food and pharmaceutical packaging sectors, accounting for 65% of total consumption, and is the main driver of overall demand growth. Other application areas account for a relatively small share and are growing at a slower pace. Ordinary plastic packaging materials used for food packaging are highly permeable to oxygen, causing food to oxidize and spoil. However, EVOH, due to its excellent oxygen barrier properties and environmental friendliness, has become an essential material in the food packaging industry. It is used in aseptic packaging, hot cans, and retort pouches for dairy products, meat, canned juices, and condiments. EVOH’s exceptional oxygen barrier properties prevent the infiltration of gases like oxygen, thus protecting packaged food and beverages from contamination and spoilage. EVOH can also be flushed into the packaging bag with nitrogen or carbon dioxide to extend food storage life and enhance flavor retention.
-Non-food packaging
EVOH not only offers excellent gas barrier properties but also excellent resistance to common organic solvents and oils, preventing their permeation. It can be used in packaging for oily foods, edible oils, mineral oils, pesticides, pharmaceuticals, health products, cosmetics, automobile fuel tanks, and organic solvents. EVOH is particularly effective in preventing spills of chemicals that pose a significant environmental risk, such as xylene, benzene, and pesticides, providing a crucial barrier.
Conclusion
The food packaging industry is always coming up with new ideas. EVOH is a material that is good for the environment. It keeps food fresh and makes sure it lasts longer. It also follows the rules of sustainable packaging. If you’re a manufacturer or brand that wants to offer high-quality products, extend shelf life and reduce environmental impact, EVOH is the answer.
