EVOH

Ethylene-Vinyl-Alcohol (EVOH), also known as EVAL: is a thermoplastic copolymer with excellent barrier properties, which makes it a widely used material in the packaging industry, especially for food.

Properties:

• Gas barrier: Gas Barrier: EVOH is impermeable to gases such as oxygen, carbon dioxide and nitrogen, ideal for packaging that needs to maintain product freshness for an extended period.
• Barrier against hydrocarbons and solvents: It is also resistant to a wide range of hydrocarbons and organic solvents, suitable for products such as beverages, pharmaceuticals and cosmetics.
• Transparency: EVOH is transparent, allowing consumers to see the product inside.
• Good mechanical resistance: It has good tensile, impact, and puncture resistance.
• Processability: It can be processed using a variety of methods, including extrusion, injection molding, and blow molding.
• Recyclable: It is a recyclable material.

Applications:

• Food packaging: Bottles, jars, trays, films, etc., for a wide range of foods, including meats, cheeses, fruits, vegetables, beverages.
• Pharmaceutical packaging: For medicines and pharmaceutical products such as vials, ampoules, and syringes.
• Cosmetic packaging: Cosméticos y productos de cuidado personal que pueden incluir tubos, frascos y botellas.
• Tubes: For products like adhesives, sealants, and putties.
• Coatings: Barrier coatings to protect metal products and other materials from corrosion and deterioration.
• Medical applications: Membranes for dialysis, catheters, and other medical devices.
