Key Advantages
-
01
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.
-
02
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.
-
03
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.
-
04
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.
-
05
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.
-
06
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.
-
07
High-temperature and low-temperature resistance: Aluminum foil bags can withstand high-temperature (121℃) and low-temperature (-50℃) environments.

Frequently Asked Questions
Got Questions? We Have AnswersWhat are the primary barrier properties of these aluminum foil bags?
The blank aluminum foil bags feature a four-layer material structure. The aluminum foil layer provides excellent barrier properties against light, oxygen, and moisture, protecting the contents from dampness, oxidation, and evaporation.
Can these aluminum foil bags be customized for anti-static requirements?
Yes, depending on your application, we can apply an anti-static liquid coating in the middle layer of the bag to ensure the safe preservation of sensitive electronic and metal components.
What is the temperature resistance range of these bags?
These bags have strong temperature resistance and remain stable in environments ranging from low temperatures of -50℃ to high temperatures of 121℃, making them suitable for refrigeration, freezing, and heat treatments.
What are the physical strength and puncture resistance ratings?
The composite structure provides outstanding physical strength. The peel strength is PET/AL≥4.5N, AL/NY≥5.2N, and NY/PE≥6.3N, ensuring excellent puncture resistance during transit.
How strong is the heat seal on these aluminum foil bags?
The heat seal strength is highly reliable, with longitudinal strength ≥ 95N and transverse strength ≥ 96N, preventing leaks and maintaining airtight security.
