Laser Burning Through Film and Damaging Aluminum? Switch to Guangdayuan‘s Laser-Marking PE Protective Film

Product Characteristic

Standard PE protective film absorbs laser energy and transfers heat to the aluminum surface, causing burns, discoloration, or pitting. This defeats traceability efforts. Guangdayuan’s laser-marking aluminum PE protective film contains specialized laser-absorbing additives. Developed with premium raw materials from Toray and Toyobo, our film converts laser energy into localized vaporization without penetrating to the metal — leaving a crisp mark on the film while the aluminum stays pristine.
