A Rainbow Effect In-Mold Label, also called an iridescent IML or color-shifting in-mold label, is a special decorative label designed to create changing colors and reflective highlights on plastic packaging.

An Orange Peel Texture In-Mold Label, also called Orange Peel Effect IML, is a special type of in-mold label designed to create a subtle textured surface on plastic packaging.

Zhejiang Zhongyu Technology Co., Ltd. has introduced a new type of Dynamic Grating In-Mold Label, designed to bring more interactive visual effects to plastic packaging.

In-mold labels (IML) are printed labels placed inside a mold before a plastic product is formed. During molding, the label becomes integrated with the container or part, creating a decorated surface without a separate post-molding labeling step.

YZY's new Star Pattern Metallized IML features an aluminum foil layer laminated inside the label film, fused into a PP cup during injection molding. The result is a crushed-glass, galaxy-grade metallic shine — already in use by top-10 Chinese tea and coffee chains. A demonstration of YZY's latest R&D capability in premium in-mold labeling.

Thermochromic in-mold labels (temperature-sensitive IML) change color at a precise trigger temperature — fused permanently into PP cups. YZY supplies thermochromic IML from -15°C to 70°C, with 15+ base colors and the option to layer thermochromic + standard inks. Perfect for hot drink warnings, cold drink indicators, kids' products, limited editions, and interactive marketing.
