Three-side seal aluminum foil bag

Three-side-seal aluminum foil bags are one of our company’s most traditional products. They are manufactured using fully automated, mechanized processes, ensuring safety and hygiene, stable product quality, high production efficiency, and excellent sealing performance. Aluminum‑plastic laminates are composite films formed by bonding three to four layers—or even more—using adhesives or lamination techniques. A typical structure is as follows: First layer: This layer provides the bag with sufficient strength under specific temperature conditions and within a defined range. Second layer: Aluminum foil, serving as a barrier layer. Its primary functions are moisture resistance, oxygen barrier properties, and light protection. Third layer: The innermost layer is the heat‑seal layer.

　　Three-side-seal aluminum foil bags are one of our company’s most traditional products, manufactured using fully automated machinery. They are safe and hygienic, with consistent product quality, high production efficiency, and excellent sealing performance.

　　Aluminum-plastic laminates are composite films formed by bonding three to four layers, or even more, together using adhesives or a lamination process. The typical structure is as follows.

　　First layer: This layer ensures the strength of the packaging bag within a specific temperature range.

　　Second layer: aluminum foil, a barrier layer. Its primary functions are to prevent moisture, block oxygen, and shield against light.

　　Third layer: The innermost layer is the heat-seal layer.
