Aluminum foil bags are produced by dry laminating aluminum with other high-barrier materials, leveraging the unique properties of aluminum. 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 blockage, and has outstanding aroma retention. Therefore, aluminum foil bags possess excellent functions such as moisture resistance, barrier protection, light blocking, penetration resistance, and an aesthetically pleasing appearance.
