Abstract

The invention relates to an aluminum-titanium foil, in particular to an aluminum-titanium foil with good antibacterial performance. The aluminum titanium foil comprises the following chemical components in percentage by weight: 0.7 to 1.1 percent of Fe, 0.2 to 0.3 percent of Si, 0.01 to 0.03 percent of Cu, 0.05 to 0.10 percent of Ti and the balance of Al and impurities. According to the aluminum-titanium foil provided by the embodiment of the invention, the weight percentage control range of Fe, Si and Cu is reduced, and the weight percentage of Ti is increased, so that the antibacterial performance of the aluminum-titanium foil can be improved, and the aluminum-titanium foil can play a good antibacterial role when being used for packaging foods or medicines.

Description

technical field [0001] This application relates to the field of packaging, in particular to an aluminum-titanium foil. Background technique [0002] At present, as human beings pay more attention to health and enhance their awareness of environmental protection, packaging materials are developing in a safer and pollution-free direction. However, the current packaging materials usually do not have antibacterial function, which can easily cause bacteria to invade food or medicine, cause food and medicine to deteriorate, breed bacteria, and threaten people's health. Contents of the invention [0003] In view of the above situation, it is necessary to provide an aluminum-titanium foil, which has good antibacterial properties. [0004] The embodiment of the present application provides an aluminum-titanium foil, the chemical composition of which is as follows: Fe: 0.7-1.1%, Si: 0.2-0.3%, Cu: 0.01-0.03%, Ti: 0.05-0.10%. The amount is Al and impurities. [0005] The aluminum-t...
