Understanding EVOH High Barrier Shrink Film: Properties and Applications

EVOH (Ethylene Vinyl Alcohol) high barrier shrink film is a specialized packaging material renowned for its superior barrier properties. This innovative film is widely used in the food and medical industries to extend shelf life, protect products from contamination, and maintain the freshness of the contents. 

Key Properties of EVOH High Barrier Shrink Film
Excellent Barrier to Gases and Moisture: EVOH high barrier shrink film offers outstanding protection against oxygen, carbon dioxide, and moisture, which is essential for preserving perishable items. The structure of EVOH allows it to block oxygen, preventing the degradation of food products and maintaining freshness for longer periods.

High Clarity and Transparency: The film's transparency and clarity make it ideal for packaging applications where product visibility is important. Consumers can easily see the contents inside the packaging, enhancing the visual appeal of the product and boosting customer confidence.

High Shrinkability: One of the most important features of EVOH high barrier shrink film is its shrinkability when exposed to heat. This characteristic ensures a tight, secure fit around the product, offering added protection from external contaminants and preventing tampering during transportation and storage.

Durability and Puncture Resistance: The film is highly durable and resistant to punctures, tears, and abrasions. This makes it suitable for packaging items with sharp edges or irregular shapes without compromising the integrity of the package.

Eco-Friendly Option: EVOH films are designed to be environmentally friendly. They are lightweight and require less material, which reduces waste. Additionally, EVOH can be used in multilayer structures, enabling recyclability and minimizing environmental impact.

Applications of EVOH High Barrier Shrink Film
Food Packaging: EVOH high barrier shrink film is widely used in the food industry for packaging fresh and processed meats, cheeses, poultry, and seafood. Its oxygen and moisture barrier properties are crucial in maintaining product freshness and preventing spoilage. The film is often employed in vacuum-sealed and modified atmosphere packaging (MAP) systems, ensuring an extended shelf life.

Medical and Pharmaceutical Packaging: EVOH shrink film is ideal for medical and pharmaceutical packaging, as it provides a sterile and protective environment. Its ability to block oxygen and moisture is essential in preserving the quality and efficacy of sensitive medical devices and drugs.

Cosmetic and Personal Care Products: For packaging cosmetics and personal care items such as lotions, creams, and perfumes, EVOH high barrier shrink film offers an effective solution. It helps protect these products from oxidation, extending their shelf life and preserving their quality.

Household Products: EVOH films are used in packaging cleaning agents, detergents, and other household products that require protection from external factors such as moisture and air.
