BENZ Aluminium barrier film refers to a type of packaging material that incorporates a layer of aluminium to provide enhanced barrier properties against light, oxygen, moisture, and other external elements. The film is designed to protect the contents of the packaging from environmental factors that could degrade its quality, freshness, or shelf life. The aluminium layer acts as a barrier that helps prevent the penetration of gases and moisture, making it particularly suitable for packaging products that are sensitive to these external factors. Common applications of aluminium barrier film include food packaging, pharmaceuticals, and other products that require protection from oxidation or deterioration.
