Products Description
Most military food packaging is made from aluminum foil materials. Food-grade aluminum foil bags are made by dry lamination using high-barrier materials like aluminum, leveraging the unique properties of aluminum.
Advantages
- Lightweight and glossy
- Strong reversibility
- Excellent barrier properties
- Impermeable to gases and water vapor
- Good temperature adaptability
- Shape stability at high and low temperatures
- Strong light-blocking capability
- Good aroma retention
Due to these advantages, aluminum retort pouches provide excellent moisture-proof, light-blocking, anti-penetration, and aesthetic functions. The water vapor transmission rate can be as low as <0.015g/m²·24h·0.1MPa, and they also have heat-sealing capabilities. They can be vacuum-packed, and composite aluminum foil bags are opaque, silver-white, and have a reflective gloss. They can be stored in environments with temperatures ≤38°C and humidity ≤90%.
