What are the functional characteristics of aluminized PET film?

Functional characteristics of aluminized PET film, PET reflective film is characterized by excellent optical properties, smooth and smooth surface, good thermal stability, low shrinkage, and light aging resistance.
Reflective materials used in transportation facilities include lens-type retroreflective film and flat-top-type reflective film. They all use aluminum-plated PET film as a reflective layer. After coating with pressure sensitive adhesive, the refractive index is 1.9 glass Beads adhere to the aluminum-plated PET film, and then spray a layer of butyral surface protection layer to form.
PET reflective film is used in billboards with reflective requirements, traffic reflective signs (reflective road signs, reflective barriers, reflective vehicle number plates), reflective police uniforms, industrial signs, etc.
