Description

Technical Field

[0001] The utility model relates to patterned material paper, in particular to waterproof and moisture-proof coated patterned material paper, belonging to the technical field of patterned material paper. Background Art

[0002] Coated patterned paper is a special type of paper that undergoes a coating process during the papermaking process, creating a decorative effect with a specific pattern or design on the surface. This paper not only inherits the smoothness, glossiness, and printability of coated paper, but also combines the decorative and aesthetic value of patterned paper. Coated patterned paper undergoes a special treatment to form a waterproof layer on the surface, effectively preventing water and moisture penetration, thereby protecting the paper's interior from dryness and stability, achieving a waterproof and moisture-proof effect. It is widely used in industries such as packaging, artwork, and home decoration.

[0003] When used as packaging, coated patterned paper can be used to make various waterproof and moisture-proof packaging boxes, gift boxes, handbags, etc. to protect products from erosion in a humid environment. However, since a waterproof layer is provided on the surface of the coated patterned paper, the waterproof layer is usually made of materials such as high molecular polymers. While these materials form a waterproof barrier, they also hinder the air permeability of the paper. Therefore, there are certain limitations when packaging products that require internal air circulation. Moreover, the addition of the waterproof layer increases the thickness and hardness of the paper and reduces the flexibility of the coated patterned paper. Therefore, a waterproof and moisture-proof coated patterned paper is proposed. Utility Model Content

[0004] The purpose of the present invention is to provide a waterproof and moisture-proof coated patterned material paper to solve one of the problems raised in the above background technology.
