Aluminum foil bag with square bottom, aluminum-plastic bag

Aluminum foil bags are produced by dry laminating aluminum with other high-barrier materials based on the unique properties of aluminum. Due to aluminum's characteristics—lightweight, glossy surface, strong reflectivity, excellent barrier properties, impermeability to gases and moisture, adaptability to temperature, shape stability under high or low temperatures, strong light-blocking ability, and superior aroma retention—aluminum foil bags offer excellent functions such as moisture resistance, barrier protection, light blocking, penetration resistance, and an aesthetically pleasing appearance.
