Everyone buys self-adhesive wallpaper online with formaldehyde, and the formaldehyde content of this wallpaper is much higher than that of wall covering bought in a specialty store. The formaldehyde of this self-adhesive wall sticker is divided into two aspects, one is from the glue on the wall sticker, and the other is from the pigment of the wallpaper itself. Although this kind of self-adhesive wallpaper is very cheap, it has poor environmental protection, poor quality and short service life.
