Introduction to color Change IML
BOPP Color Change IML is an intelligent In-Mold Label (IML) that uses BOPP film as a substrate and incorporates temperature- or light-changing materials that change color in response to external stimuli (eg., temperature, UV light) to achieve dynamic visual effects
Main material composition:
1.BOPP base film (bi-oriented polypropylene) high transparency, strong toughness, suitable for fine printing and in-mold labeling process. High temperature and humidity resistance, suitable for food, daily chemical and other packaging.
2. Color changing materials (temperature change/light change ink) change color with temperature change and recover after cooling.
3. Printing layer & protective coating - can be customized pattern, accurate positioning of the color change part (such as logo, border, etc.).
Wear-resistant coating to prevent scratches and extend the life of the color change.
