Aluminium Foil 8011-O For Soft Temper Lamination
Coffee, as a popular leisure office drink, needs to be packaged and stored with high-barrier packaging materials such as aluminum foil composite packaging bags, and often nitrogen-filled packaging or modified atmosphere packaging is used to ensure an oxygen-free or low-oxygen environment inside and avoid coffee It is oxidized and deteriorated. However, the barrier properties of the packaging materials to the nitrogen or carbon dioxide filled in the above-mentioned packaging forms require professional detection equipment and related detection methods to monitor, so as to ensure that the internal gas is not easily lost.

Food uses plastic and aluminum foil composite film as packaging bag, which has high barrier properties to O2 and H2O and good light-shielding properties. As the barrier layer in the middle of the composite film, aluminum foil has high barrier properties to O2, CO2, N2, air, and H2O. Therefore, when the composite film containing aluminum foil is used as a coffee packaging bag, it is under a standard environment of 23°C and 0%RH The oxygen transmission rate (ie oxygen barrier) can reach 0.05 cm3/(m2∙24h∙0.1MPa), and the water vapor transmission rate (ie moisture barrier) can reach 0.01 g/ at 38℃ and 90%RH. (m2∙24h). However, in order to extend the coffee shelf life and ensure the sensory quality of coffee, aluminum foil composite film bags of coffee often use nitrogen-filled packaging or modified atmosphere packaging to meet the anaerobic or low-oxygen storage environment of coffee.
This is htmm Reasons for providing clean foil. Clean aluminum foil has little pollution. This means that the aluminum foil is grade "a" wettable and completely free of oil commonly found on other grades of aluminum foil. Our UHV foil is produced on plastic core. Each UHV roll is also packaged in a free plastic distribution box and wrapped with film. This is important for customers who need little or no pollution penetration into the environment. All foils will demonstrate that our clean aluminum foil / UHV foil meets the specifications specified by the American Society for testing and materials (ASTM)
