At present, the major wallpapers in the building materials market mainly include PVC, pure paper and fiber “three major families”, of which PVC is the main one, which accounts for about 80% of the market share. PVC wallpaper is rich in color variety, scrub resistance, mildew resistance, anti-aging, not fade, and other advantages, moderate price, more respected in the market; but PVC wallpaper is easy to curl, produce bubbles and mildew. Pure paper wallpaper is characterized by PVC-free, odorless, and good air permeability.

Fiber wallpaper with PVC wallpaper can be scrubbed, not easy to fade, folding, mildew and other characteristics, but the price is higher.

Its paper base has higher strength, flexibility and embossing process. The wallpaper of moderate price is mainly produced in South Korea, Japan, etc. The price is about 100 yuan per volume. The colors and patterns are more suitable for Chinese people's aesthetics. The price of domestic wallpaper is relatively low. Basically, the price is between 30 yuan and 60 yuan per roll. The appearance quality of the wallpaper does not look much different from that of imported wallpaper, but the strength, flexibility, PVC thickness and pressure of the paper base are similar. There is still a certain gap in the level of flower craftsmanship.

Because wallpapers often use a large amount of glue in the production process, formaldehyde, vinyl chloride, etc. will have certain residues. This is the main source of wallpaper pollution and will undoubtedly pose a threat to human health. There are many inferior wallpapers on the market. After using them, in addition to producing quality problems, harmful gases released from them will harm the human body.
