Aluminum foil bags are produced by dry laminating aluminum with other high-barrier materials, leveraging aluminum's unique properties. Aluminum is lightweight, glossy, highly reflective, offers excellent barrier properties, is impermeable to gases and moisture, adapts well to temperature variations, maintains shape stability under high or low temperatures, provides strong light-blocking, and has superior aroma retention. Therefore, aluminum foil bags feature excellent moisture resistance, barrier protection, light avoidance, penetration resistance, and an aesthetically pleasing appearance.
