Which pigment is commonly recognized as one of the most widely used in packaging?

Titanium dioxide is widely recognized as one of the most commonly used pigments in packaging due to its outstanding properties. It is known for its excellent opacity, brightness, and durability, making it ideal for a variety of packaging materials. The pigment helps achieve a bright white color, which can enhance the appearance of printed graphics and protect products from UV light, thereby extending shelf life. Its non-toxic nature also contributes to its popularity in food packaging, where safety is a critical concern.

In contrast, while cyan and ultramarine blue are important pigments in various applications, they are not as prevalent in packaging material as titanium dioxide. Chrome yellow, although used in some applications, has been replaced in many cases due to safety concerns related to chromium compounds. This demonstrates why titanium dioxide stands out as the preferred choice in the packaging industry for producing high-quality, visually appealing, and safe products.
