What is EVOH Barrier Film?

EVOH, or ethylene vinyl alcohol, is a thermoplastic polymer renowned for its superior barrier properties. It primarily functions by preventing the permeation of gases like oxygen and carbon dioxide and offering significant moisture resistance. Its applications are widespread due to its ability to enhance shelf life and product quality.

Key Characteristics of EVOH Barrier Film

• Oxygen Barrier: Protects against oxidative spoilage.
• Moisture Resistance: Prevents mold and spoilage due to humidity.
• Clarity: Provides excellent visibility of the product inside the packaging.
• Recyclability: Can often be recycled, helping reduce environmental impact.

Common Applications of EVOH Barrier Film

EVOH barrier film is employed in various sectors, each benefiting from its unique properties:

1. Food Packaging

   • Extends shelf life of perishable goods.
   • Maintains flavor and nutritional content.

2. Pharmaceuticals

   • Safeguards sensitive ingredients.
   • Ensures compliance with stringent regulations.

3. Industrial Products

   • Used in packaging construction materials.
   • Protects against moisture and gases that can compromise quality.

Benefits of Using EVOH Barrier Film

Utilizing EVOH barrier film brings about several advantages for manufacturers and consumers alike:
