Composite membranes are multilayered materials used in packaging to provide effective barriers against gases, moisture, and light. These membranes combine different materials, such as plastics, aluminum, and paper, to achieve specific protective properties.

The structure of composite membranes allows for flexibility, durability, and resistance to punctures, making them suitable for packaging perishable products. Common applications include food packaging, medical supplies, and industrial materials.

Composite membranes can be engineered to provide high barrier performance while maintaining lightweight and easy-to-handle characteristics. They can also be used in laminates or as inner layers within bags or pouches to enhance product protection.

Proper handling and storage of composite membranes are important to preserve their integrity before use. By integrating multiple materials, composite membranes offer a reliable solution for maintaining product quality and extending shelf life, meeting the requirements of various industries.
