Scope of application of high barrier packaging bags

High barrier packaging bags, with their excellent barrier properties, have become an ideal choice for modern food, pharmaceutical, and industrial product packaging. This type of packaging bag usually uses multi-layer co extrusion technology to melt and extrude resin materials with different functions, forming a multi-layer structural film with excellent barrier properties.

texture of material:

The main materials of high barrier packaging bags include PVDC (polyvinylidene chloride), EVOH (ethylene vinyl alcohol copolymer), nylon (PA), etc. PVDC is known for its low permeability, barrier properties, and chemical resistance, which can effectively prevent the penetration of gases such as oxygen and water vapor. EVOH has excellent oxygen and water resistance properties, as well as good chemical stability. Nylon film has high strength and toughness, good impact resistance, and excellent barrier properties. These materials are compounded in multiple layers to form high barrier packaging bags with multiple barrier properties.

Scope of application:

High barrier packaging bags are widely used in fields such as food, medicine, and industrial products. In the food industry, it can be used for packaging perishable foods such as meat, dairy products, seafood, baked goods, etc., effectively extending the shelf life of food and maintaining its freshness and quality. In the pharmaceutical industry, high barrier packaging bags can be used for moisture-proof and oxidation resistant packaging of drugs, ensuring their stability and effectiveness. In addition, it can also be used for moisture-proof and dust-proof packaging of industrial products such as electronic devices and chemicals, protecting products from external environmental damage.

In short, high barrier packaging bags have become an important component of the modern packaging industry due to their excellent barrier properties and wide range of applications.
