How to Distinguish the Authenticity of 3M Car Film?
2 Answers
Methods to identify the authenticity of 3M car film include: observing the appearance of the heat-insulating film, smelling the film up close, and paying close attention to the film application effect. The specific details are as follows: 1. Observe the appearance of the heat-insulating film: Inferior films usually have a darker color to block a large amount of visible light. After exposure to sunlight, the color of the film will fade, mainly because the adhesive layer of the film volatilizes after exposure, causing color changes. More alarmingly, inferior films use ordinary, cheap materials and curing processes, which can partially melt under sunlight, causing optical distortion and posing significant driving hazards. 2. Smell the film up close: You can ask the store for scraps of the heat-insulating film and smell them up close. If you detect a strong, pungent odor, it can basically be judged as an inferior film, mainly due to the use of harmful chemical adhesive layers during the film manufacturing process.
I've encountered fake 3M car window film several times, which faded early and provided no heat insulation. Later, I learned some tips to distinguish the genuine from the fake. The most straightforward way is to check the packaging box. The genuine product has high-definition printing with no blurry fonts or incorrect punctuation marks, and there's an anti-counterfeit label with a QR code next to it. Scanning it will take you to the official 3M website for verification. The film itself should feel smooth and fine, without bubbles or impurities. After installation, test the UV protection effect—genuine film blocks UV rays well, keeping the car interior cool. The purchase location is also crucial; always choose official authorized stores or reputable shops, and avoid buying from cheap online stores. Remember, fake film not only wastes money but also poses risks by affecting window visibility. It's advisable to spend extra time checking carefully.
