Tactile coating application: Tactile oil/coatings containing polyurethane, silicone, wax emulsion, etc. are evenly applied to the paper surface through micro-concave, scraper or flexographic coating. The wet film thickness is 5-20 μm, which determines the final tactile feel (velvety feel, silky smooth, rubber-like feel, etc.).
Embossing/calendering: Use a textured metal roller or elastic roller to perform embossing or calendering at 80-120 ℃ and 50-150 bar to create a fine texture or mirror-like smoothness. Cold calendering retains the matte and velvety feel.
Lamination/composite: Composite PET, PP film or non-woven fabric to enhance wear resistance, scratch resistance and water resistance, suitable for scenarios that require strong protection.
Flocking: Electrostatic flocking enables nylon and viscose short fibers (0.1-0.5mm) to adhere vertically, creating a velvety touch, and is often used in high-end gift boxes.
