Traditional wooden furniture is made of melamine with PVC banding. PVC banding uses glue as adhesive, which is easy to peel off after a long time. In an extreme humid weather or environment, water vapor is easy to enter the MDF, causing problems such as expansion, cracking and molding of the board. Free formaldehyde in the board will also take the opportunity to release and endanger family health. The elderly and children have low immunity, and are more likely to become victims of free formaldehyde. Therefore, it is urgent to choose truly environment-friendly furniture.
