How to Identify Genuine 3M Film?
1 Answers
Here are the methods to identify genuine 3M film: 1. Check the Adhesiveness: Genuine 3M car film is a pressure-sensitive film, and its adhesive properties only become apparent under continuous external pressure. In contrast, counterfeit products on the market are usually ordinary adhesive films that feel sticky without any external pressure. 2. Examine the Roller: The roller of genuine 3M car film is made of high-quality plastic, giving it a solid and thick texture when touched. However, most counterfeit products use cardboard rollers. 3. Look for the Logo: The 3M logo is visible on the film. For genuine 3M film, the logo is difficult to scrape off with a fingernail and requires professional cleaning agents or alcohol to remove. In contrast, the logo on counterfeit films can be easily scratched off with a fingernail. 4. Inspect the Red Core: Genuine 3M car film has a red 3M label on the red core. Once this label is torn off, it is considered damaged and cannot be replicated. Counterfeit films allow the label to be peeled off and reattached. 5. Observe for Bubbles: After peeling off the plastic liner of the film and reattaching it, genuine 3M film will reattach completely without any visible bubbles, feeling thick and smooth to the touch. Many counterfeit 3M films will show numerous tiny bubbles after reattachment, feeling thin and brittle. Additionally, when viewed from the side after application, genuine 3M film has a fine and smooth surface texture, while counterfeit films have a noticeably rougher texture.
