Protective films are thin layers of material designed to shield surfaces from damage, scratches, and contaminants. Commonly made from materials like polyurethane or polyethylene, these films can be applied to various items, including electronics, vehicles, and furniture. They help maintain the appearance and longevity of products by acting as a barrier against wear and tear. These films are often transparent, allowing the original surface to remain visible while providing protection. They can be easily removed without leaving residue, making them a popular choice for consumers looking to preserve the quality of their belongings, such as smartphones and automobiles.
