In today’s competitive packaging landscape, material performance is critical to ensuring product integrity, freshness, and safety. EVOH: Barrier Resins for Packaging (Ethylene Vinyl Alcohol) Barrier Resins have become an industry standard for delivering unmatched oxygen and gas barrier properties. Designed to protect sensitive products across food, medical, and industrial sectors, EVOH helps manufacturers achieve longer shelf life, superior product safety, and reduced environmental impact. A&D Polymers proudly offers premium EVOH resins tailored to the evolving needs of modern packaging.

Key Features and Properties

Exceptional Barrier Performance

EVOH resins provide outstanding resistance to oxygen, carbon dioxide, and organic solvents. This minimizes oxidation and aroma loss, critical for maintaining the quality of packaged goods.

High Transparency and Gloss

Products packaged using EVOH benefit from excellent clarity and an appealing surface finish, making them ideal for consumer-facing packaging where appearance matters.

Versatility in Processing

EVOH can be processed through co-extrusion, co-injection molding, and lamination techniques, ensuring compatibility with a variety of manufacturing technologies.

Chemical Resistance

EVOH exhibits excellent resistance to oils, fats, and a wide range of chemicals, making it suitable for aggressive contents like medical fluids, industrial oils, and fatty foods.

Moisture Sensitivity and Protective Layers

While EVOH is sensitive to moisture, combining it with protective outer layers like polyethylene or polypropylene in multilayer structures effectively preserves its barrier properties.

Applications and Industries Served

Food Packaging

EVOH is widely used in multilayer packaging for meat, dairy products, sauces, baby food, and ready-to-eat meals. Its superior barrier properties keep food fresher longer, reducing spoilage and waste.

Medical and Pharmaceutical Packaging

Medical devices, pharmaceutical products, and diagnostic kits require packaging that prevents oxygen ingress. EVOH provides the necessary protection to maintain sterility and efficacy.

Industrial Packaging

For sensitive industrial materials like lubricants, chemicals, and agricultural products, EVOH ensures extended shelf life and performance stability, even under harsh conditions.

Sustainable Packaging Initiatives

Due to its effectiveness at very thin layers, EVOH contributes to material reduction strategies, aligning with eco-friendly packaging goals without sacrificing protection.

Benefits and Competitive Advantages of EVOH: Barrier Resins for Packaging

Extended Shelf Life

By dramatically reducing oxygen transmission, EVOH helps extend the shelf life of perishable goods, leading to fewer returns, improved customer satisfaction, and better supply chain management.

Cost-Efficiency through Material Optimization

Thanks to its high performance at low thickness, EVOH allows for lighter, more sustainable packaging structures without compromising on functionality.

Customizable Solutions

A&D Polymers offers EVOH grades that can be fine-tuned for specific processing methods and end-use requirements, ensuring that clients receive solutions perfectly suited to their applications.

Regulatory Compliance

Our EVOH resins comply with global food contact and pharmaceutical safety standards, providing peace of mind and facilitating international market access.
