Precautions for aluminum labels need to be addressed according to their application scenarios (such as signage, food contact, cosmetics, anti-theft labels, etc.).
Surface Cleaning: Before pasting, ensure the surface is free of oil and dust to guarantee adhesive adhesion.
Avoid acidic and alkaline environments: Although aluminum is corrosion-resistant, it may react under strong acid or alkaline conditions, causing label damage.
Moisture and Salt Spray Protection: Chloride ions (such as seawater and salt water) will damage the oxide film on the aluminum surface, accelerating corrosion; prolonged contact is not recommended.
Installation methods: Double-sided adhesive on the back is suitable for flat surfaces such as appliances and furniture; Drilling or punching installation is suitable for mechanical equipment and other scenarios requiring secure fixing.
