Many car owners will consider applying film to their cars after buying them, but how should they choose car glass film? Which kind of film is worth applying? Today, I will explain to you the past and present of glass film and how to choose it.

First generation: dyed film (tea paper);
Time: late 1970s;

Material: dye;

Process: dyeing process;

Advantages: anti-glare;

Disadvantages: harmful to health; no heat insulation; short life, easy to fade (about 1-2 years); blistering;

Second generation: single-layer metal reflective film;
Time: early 1980s;
Material: cheap metal (aluminum, titanium);
Process: evaporation process;
Advantages: low light transmittance, can block some heat;
Disadvantages: mirror appearance, easy to cause light pollution; uneven metal layer, blurred vision; low heat insulation when transparent, low transparency when heat insulation; easy to oxidize;

The third generation: heat-absorbing film;
Time: late 1980s;
Material: infrared absorber;
Process: coating process;
Advantages: temporary heat insulation;
Disadvantages: health hazards; low cost performance; false heat insulation;

Fourth generation: intelligent spectrally selective film;
Time: early 1990s;

Material: precious metals (gold, silver, indium oxide);

Process: magnetron sputtering process (XIR);

Advantages: high transparency and high clarity; high reflection of infrared rays; low reflection;

Disadvantages: customers who have not experienced it feel that the price is slightly high;
