The blank aluminum foil bag is made up of four layers of material, with the aluminum foil layer providing excellent light, oxygen, and moisture barrier properties, effectively preventing the contents from getting damp, oxidizing, or evaporating.
Aluminum foil bags can block ultraviolet rays, protecting sensitive products. Depending on the use, the process in the middle of the aluminum foil bag can be added, for example, aluminum foil bags for metal components are coated with anti-static liquid to ensure the good preservation of metal components.
Aluminum foil bags remain stable over a wide range of temperatures, effectively protecting the contents from environmental temperature changes, whether for frozen food, refrigerated storage, or heat treatment, suitable for quick-frozen food, ready-to-eat products, etc.
The composite structure endows the aluminum foil bag with good physical strength and puncture resistance, effectively preventing damage during transportation and storage, protecting the safety of internal goods.
The surface of the aluminum foil bag is easy to print, allowing for exquisite patterns and text, enhancing the product's appearance appeal, increasing brand recognition, suitable for high-end product packaging.
Although aluminum foil itself is not degradable, its excellent barrier properties can reduce the overall use of packaging materials, and aluminum can be recycled, in line with modern environmental protection concepts.
Aluminum foil bags can withstand high-temperature (121℃) and low-temperature (-50℃) environments.
