1. Exceptional Whiteness & Brightness: Provides a pristine, ultra-clean white canvas with 90%+ ISO brightness, ensuring cosmetic brands look immaculate.
2. Flawless Print Reproduction: Coated with clay coatings that allow high-resolution offset printing, ultra-fine typography, and vibrant Pantone ink matching.
3. Superior Embossing & Foil Stamping: The virgin pulp fibers hold crisp emboss reliefs and sharp metallic foil stamping lines without cracking.
4. Odorless & Pure: Virgin chemical pulp is free from recycled contaminants and neutral in odor, making it safe for skincare, beauty, and food.
