(1) Ordinary Wallpaper Ordinary wallpaper is typically made from a base of 80g/m² paper, coated with 100g/m² of PVC paste resin, and then printed and embossed. This type of wallpaper comes in several varieties, including flat light printing, light printing, single-color embossing, and printed embossing. Common patterns include wood grain, marble, and raised textures. However, ordinary wallpaper has some disadvantages. It tends to be less durable, not resistant to moisture or water, and cannot be easily cleaned. These limitations can make it inconvenient for long-term use after decoration. (2) Foam Wallpaper Foam wallpaper is created using 100g/m² paper as the base, coated with 300-400g/m² of PVC paste resin that contains a foaming agent, and then foamed during the printing process. Compared to ordinary wallpaper, foam wallpaper is thicker and softer. There are different types, such as high-foam printed, low-foam printed, and foam-printed embossed wallpapers. High-foam wallpaper offers an elastic, three-dimensional texture, making it ideal for both decoration and sound absorption. Low-foam wallpaper features vivid, realistic patterns like imitation wood, mosaics, and tile designs, creating a strong sense of depth and visual appeal. It's often used in areas like wall skirts, living rooms, and corridors, where aesthetics and durability matter.
