The protective film for particle board, also known as MDF (Medium Density Fiberboard) protective film, is a thin, transparent layer that is applied to the surface of the board to safeguard it from scratches, dust, dirt, and other potential damage during handling, transportation, and installation. This film is typically made from polyethylene or other durable materials and can be easily peeled off after the board is in place. It helps maintain the pristine appearance of the board and prevents surface blemishes, ensuring the quality of the product remains intact until it is ready for use. Additionally, it can provide moisture resistance, adding another layer of protection, especially in environments with high humidity.
