The aluminum alloy zipper is more susceptible to corrosion, so it should be kept dry and not exposed to moisture to prevent the aluminum teeth from forming white oxides, which will cause the zipper to rust over time and affect the use. contact with acidic substances. When storing, ensure a certain degree of ventilation, do not seal it, and do not store it in a humid environment. If necessary, use moisture-proof paper or dehumidifier.
