Abstract

The invention belongs to the technical field of special paper manufacturing, particularly relates to leatherette paper with a pasting effect, and a preparation process thereof, and solves the problems that leatherette paper in the prior art is not good in surface sensory degree, not ideal in surface skid resistance, stain resistance and water resistance, does not have the pasting effect and cannot meet the requirements in the use process. The leatherette paper with the pasting effect is composed of body paper, a treating fluid, a bottom coating and a surface coating. After the body paper is subjected to dipping treatment by utilizing the treating fluid, one side of the body paper is coated with the bottom coating, the other side of the body paper is coated with the surface coating, and drying is performed to obtain the leatherette paper. The preparation process is simple, the preparation condition is mild, the preparation efficiency is high, and the obtained leatherette paper has good waterproof, antifouling, antibacterial and mildew-proof effects, has leather texture, soft and loose feeling, high glossiness, random folding, good folding resistance and wear resistance and no linting and dusting phenomena, and can be widely applied to packaging of various high-grade products.

Description

technical field [0001] The invention relates to the technical field of special paper manufacturing, in particular to leather-filled paper with sticking effect and a preparation process thereof. Background technique [0002] With the development of papermaking technology and subsequent paper deep processing, paper plays an increasingly important role in the packaging industry. Vellum paper is a popular environmentally friendly packaging paper in the world. Its paper is soft and has a leather feel. The surface layer is wear-resistant and fold-resistant. It uses environmentally friendly water-based inks. It has a variety of colors and patterns. Different colors, textures and gloss levels make the paper ever-changing. , Or elegant or fashionable, the products are suitable for all kinds of high-end packaging such as gift boxes, jewelry boxes, jewelry boxes, books, album binding covers, high-end gift boxes, wine boxes, tea boxes, notebooks, bags, collectibles, etc. [0003] With ...
