EVOH is renowned for its high barrier properties, particularly its ability to prevent the permeation of gases, water vapour, and organic compounds such as aromas.EVOH is widely used in combination with other materials such as PP ,PET , and PVC to create composite materials that offer an effective combination of strength, flexibility, and superior barrier properties.EVOH's exceptional barrier properties make it an ideal choice for packaging perishable food products such as dairy items,ready-to-eat meals, snacks, and beverages. EVOH prevents the diffusion of oxygen, which helps prevent spoilage and preserves thequality of food. Additionally, it provides protection against carbon dioxide, nitrogen, and volatile organic compounds (VOCs),furtherextending shelf life and ensuring the product's freshness.
