Temperature-sensitive labels are specialized stickers that change color or appearance based on temperature fluctuations. These labels are often used in various industries, such as food and pharmaceuticals, to monitor the temperature of products during storage and transportation. They help ensure that items remain within safe temperature ranges, providing a visual cue if conditions become unsuitable. These labels typically contain thermochromic materials that react to heat. When the temperature exceeds a certain threshold, the label changes color, indicating potential spoilage or degradation. This feature helps businesses maintain quality control and ensures consumer safety by preventing the use of compromised products.
