PA EVOH PE High Barrier Stretch Roll Film for Food Packaging

EVOH high barrier flexible packaging film is the core choice for food freshness. As the "Barrier King", EVOH film has extreme gas barrier properties due to tight hydrogen bonds formed by hydroxyl groups in its molecular structure, especially excellent oxygen barrier capacity, far superior to PA, PP and PE under dry conditions.

At 23℃ and 50% relative humidity, the barrier layer above 20μm can reduce the oxygen transmission rate of the composite film to 1.0~1.5 ml/m²·24h, comparable to aluminum foil, fundamentally preventing food oxidation and deterioration. The multi-layer composite process solves its humidity sensitivity, wrapped with moisture-proof materials such as PE and PP, extending food shelf life without excessive preservatives, suitable for fresh food, dairy products, quick-frozen food and other scenarios.

It also isolates moisture and peculiar smell, locks the original flavor of food. With high transparency, easy processability and environmental protection, it adapts to various packaging needs, is non-toxic and recyclable, conforms to green trends, and builds a quality line for food enterprises.

Jinde Packaging — a National High-Tech Enterprise, a Provincial-level Specialized, Refined, Characteristic and Novel SME, and a Provincial-level Green Factory — has been deeply engaged in the packaging field and meticulously crafted EVOH food flexible packaging films to guard the true flavor of food with high barrier performance. Its core barrier layer, EVOH, features a dense molecular structure, with oxygen barrier property far superior to traditional materials such as PE and PP. It can effectively block gas penetration, delay food oxidation and deterioration, and greatly extend the freshness period. Relying on advanced multi-layer co-extrusion technology, it balances moisture resistance and stability, suitable for packaging of all types of food. With strict quality control and large-scale production capacity, Jinde gives full play to the high barrier advantage of EVOH, providing safe and long-acting freshness-locking solutions for the food industry and building a solid fresh-keeping line of defense for food with professional strength.
