A screen protector film is a thin layer of material designed to cover and protect the display of electronic devices like smartphones, tablets, and laptops. Made from materials such as plastic or tempered glass, it helps prevent scratches, smudges, and minor impacts, ensuring the screen remains clear and functional. These films are typically easy to apply and can be removed without leaving residue. Some screen protector films also offer additional features, such as anti-glare or privacy protection, which can enhance the user experience by reducing reflections or limiting visibility from side angles.
