Product Features
- Excellent barrier properties: 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.
- Tailored to the process: 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.
- Strong temperature resistance: 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.
- Mechanical strength and puncture resistance: 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.
- Printing adaptability: 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.
- Environmentally sustainable: 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.
- High-temperature and low-temperature resistance: Aluminum foil bags can withstand high-temperature (121℃) and low-temperature (-50℃) environments.

Frequently Asked Questions
What are the primary barrier properties of blank aluminum foil bags?
Blank aluminum foil bags feature a specialized four-layer material structure. The integrated aluminum foil layer delivers outstanding resistance to light, oxygen, and moisture, preventing contamination, oxidation, or evaporation of the packaged goods.
What is the temperature range resistance of these foil bags?
These bags offer exceptional thermal stability, designed to withstand high-temperature environments of up to 121°C as well as low-temperature freezing conditions down to -50°C.
What are the measurement parameters for peel and heat seal strength?
The peel strength of the composite layers measures PET/AL ≥ 4.5N, AL/NY ≥ 5.2N, and NY/PE ≥ 6.3N. The heat seal strength measures longitudinal ≥ 95N and transverse ≥ 96N, ensuring strong puncture and stress resistance.
Can these packaging bags be customized with anti-static coatings?
Yes. Depending on your packaging requirements, the inner structure of the aluminum foil bag can be coated with a specialized anti-static liquid, which is highly recommended for storing sensitive metal components and electronic parts.
Are blank aluminum foil bags environmentally friendly?
Yes, they align with modern environmental protection concepts. Although raw aluminum foil is not biodegradable, the bag's superior barrier properties reduce the overall amount of packaging material required, and the aluminum layer can be recycled.
