If you’re referring to airport security or similar screening procedures, placing window film or any other non-metallic object through a security scanner typically doesn’t cause any issues. Security scanners at airports and other checkpoints are designed to detect metallic objects, explosives, and other prohibited items, but they do not typically react to non-metallic materials like window film.

However, it’s essential to note that security procedures and requirements may vary depending on the specific location, type of security checkpoint, and the discretion of security personnel. While window film itself is unlikely to trigger any alarms or concerns during screening, it’s always a good idea to comply with any instructions or requests from security personnel and be prepared to provide information or clarification if needed.

If you’re traveling with window film or other similar materials, it’s a good idea to pack them securely in your luggage or carry-on bag and be prepared to answer any questions from security personnel about the contents of your belongings. In most cases, as long as the item does not pose a security risk or violate any regulations, it should pass through security screening without any issues.
