What is the Difference Between Dyed Film and Metalized Film?

[VanHannah]

The differences between dyed film and metalized film are as follows: 1. Texture: Dyed film uses ordinary polyester film as the base material. Due to its loose internal structure, it is easily dyed but has low strength, lacking elasticity and toughness. It feels flimsy, prone to wrinkling, and fails to meet the basic safety and anti-theft requirements of automotive films. In contrast, metalized film uses optical-grade polyester film, mostly in neutral colors, and feels thick, smooth, and dense with high strength, offering superior safety and excellent anti-theft performance. 2. Odor: Dyed film typically uses inferior adhesive containing large amounts of benzene and formaldehyde molecules, which volatilize under sunlight, producing a strong, pungent odor. Moreover, low-quality films often employ dyeing processes with many chemical pigments. Under sunlight, these pigments can chemically decompose, potentially releasing toxic substances that severely pollute the in-car air and harm the health of passengers. Metalized film uses PSA adhesive, which is colorless and has a faint odor, costing several times more than inferior adhesives.
