Here are some key aspects to consider when identifying the quality and type of wallpaper:
1. First, determine the material type—whether it's natural or synthetic (such as PVC). A simple way to tell is by burning a small sample. Natural materials typically burn without a strong odor and produce white, powdery ash. In contrast, synthetic materials like PVC will emit a noticeable smell, produce black smoke, and leave behind black, globular residue.
2. Test the color fastness by gently scrubbing the surface with a damp cloth or water. High-quality wallpaper should resist fading or losing color during this process.
3. Look for eco-friendly options that are safe and non-toxic. When shopping, take a close sniff of the product. If there’s a strong chemical smell, it may contain harmful substances like toluene or ethylbenzene, which can be dangerous over time.
4. Check the durability of the color. The surface coating and printing pigments should be carefully selected and controlled to prevent yellowing, especially in light-colored or white wallpapers that are exposed to sunlight for long periods.
5. Evaluate the design uniqueness and craftsmanship. A high-quality wallpaper should have a distinctive pattern and excellent production quality, showing attention to detail in its manufacturing process.
