EVOH (Ethylene Vinyl Alcohol Copolymer) is considered to be a more environmentally friendly material, mainly in terms of its advantages in reducing food waste, prolonging product freshness, and in the recycling process.EVOH's gas barrier properties are excellent, and it can effectively prevent oxygen, water vapor, and other substances from entering into the package, thus prolonging the shelf-life of the food, and reducing food spoilage and waste. This feature makes EVOH particularly important in food packaging, and can significantly reduce the environmental burden caused by food expiration or spoilage.
In addition, EVOH has good recyclability, and although its recyclability is not as good as that of materials such as PE (polyethylene) and PP (polypropylene), it can be used in combination with these materials to take advantage of the strengths of both materials; PE and PP have better mechanical strength and chemical resistance, while EVOH provides a better barrier to gases. Through composite use, this multi-layer packaging material ensures packaging functionality while allowing for easier disposal during recycling, helping to reduce resource waste.
What's more, EVOH is produced in a relatively environmentally friendly manner and does not release harmful substances during its use. Compared to other traditional plastic materials, the use of EVOH reduces the need for chemical additives, further minimizing the impact on the environment. Therefore, EVOH is playing an increasingly important role in promoting green packaging and circular economy, becoming an environmentally friendly and sustainable packaging material.
