The corrosion resistance of AM color labels depends on the materials used and the outer coating. Typically, AM labels consist of a plastic shell and an electromagnetic induction chip. The shell material is usually polyester or polypropylene, which offer some corrosion resistance.
	
Key factors for label corrosion resistance:
Shell Material:
Polyester: PET material itself has good chemical and corrosion resistance, resisting certain acids, alkalis, and moisture. It is commonly used in electronic devices and label shells.
Polypropylene: PP also has good corrosion resistance, especially when in contact with weak acids or alkalis.
	
Coating Protection:
UV Coating: Some AM labels have a UV-resistant coating, which not only protects the label from UV damage but also enhances its corrosion resistance.
Waterproof Coating: Some labels have an additional waterproof layer, better preventing moisture damage, especially in humid environments, extending their lifespan.
Chip Encapsulation: The electromagnetic chip inside the label is usually well-encapsulated to prevent corrosive liquids from entering the chip area, ensuring long-term stable operation.
	
Environmental Impacts:
Moisture and Chemicals: While most AM labels possess some degree of corrosion resistance, this resistance can be compromised in extreme environments.
High Temperature: Prolonged exposure to high temperatures can also cause label materials to age, affecting their performance.
	
Summary: AM color labels typically exhibit some corrosion resistance in everyday environments, especially in retail settings, and can withstand common environmental factors such as moisture and dust. However, long-term exposure to extreme chemical or temperature/humidity conditions may shorten their lifespan.
