AI Technical Summary
Traditional cigarette tipping paper is unable to meet the needs of high-end cigarette brands for complex colors such as gradients and metallic luster, and lacks a sense of layering, thus failing to reflect a high-end positioning.
The material employs a combination structure consisting of a thermochromic color-developing layer, an anti-UV layer, a toughening layer, and a high-transparency, low-haze coating on the outer side of the substrate layer. It utilizes microcapsule thermochromic particles to achieve temperature-triggered color development, and enhances protection and light transmittance through acrylic film and nano-silica film layers, while combining a pearlescent ink layer to achieve light interference effect.
It achieves temperature-triggered color development, enhances the lifespan of the color development layer, ensures no color degradation, and improves visual depth through light interference effects.
