Abstract

The invention discloses novel anti-microbial edible aluminum foil. The anti-microbial edible aluminum foil comprises, by mass percentage, less than or equal to 0.16% of Si, 0.80-1.70% of Fe, 0.08-0.17% of Cu, less than or equal to 0.4% of Mn, less than or equal to 0.04% of Mg, less than or equal to 0.06% of Zn, less than or equal to 0.06% of Ti, 0.05-0.10% of Y and the balance Al and inevitable impurities, wherein each type of other impurity elements accounts for less than 0.05%, and the total of other impurity elements is less than 0.15%. The anti-microbial edible aluminum foil has excellentanti-microbial ability for bacteria and fungi; the anti-microbial rate is higher than 99.5%; the production procedure is simplified; pollution caused in the production process and the packaging process can be prevented; no precious metal is adopted in raw materials; and the production cost is lowered.

Description

technical field [0001] The invention relates to the field of aluminum alloy materials, in particular to a novel antibacterial edible aluminum foil. Background technique [0002] Existing antibacterial aluminum foils used in air-conditioning pipes, heat exchangers, and pharmaceutical packaging are all coated with antibacterial coatings on the surface of the aluminum foil to achieve antibacterial effects. However, there are few products with antibacterial capabilities in the field of edible aluminum foil. The antibacterial coating in aluminum foil inevitably has the hidden danger of microbial contamination in the production and packaging process, and the production cost of antibacterial coating is relatively high; in order to reduce the degree of contamination, the cleanliness of the production workshop is required to be higher. Therefore, if the edible aluminum foil with its own antibacterial ability can be developed, the production process can be simplified, the production e...
