Protective films are thin layers of material designed to shield surfaces from damage. They can be made from various substances, such as polyethylene or polyurethane, and are often used on items like smartphones, tablets, and automobiles. These films help prevent scratches, dirt, and other wear and tear, extending the life of the products they cover. In addition to protecting surfaces, some protective films also offer features like UV resistance and anti-glare properties. This makes them ideal for use on windows and displays, enhancing visibility while keeping harmful rays at bay. Overall, protective films are a simple yet effective way to maintain the appearance and functionality of valuable items.
