Although the ultraviolet rays in the sun are invisible, they are extremely harmful to the human body. Excessive ultraviolet radiation will burn the skin and cause diseases. In addition, ultraviolet rays are also likely to cause accelerated aging of various vehicle interior parts such as dashboards. Therefore, the general high-quality car film has a very high UV blocking rate, while many inferior films do not have this indicator, or are far below the standard.

High-quality car film can obviously block heat radiation. The outside of the box can be judged by the feeling of the hand.
6. A good film can generally be used normally for 5 to 6 years. Some brands of film have a film warranty card, remember to ask for it from the merchant; and for the film without a warranty card, you must keep various documents and invoices, so that you can find a “theory” from the merchant when there is a problem.
