In the field of automotive supplies, the development of automotive window film has always been centred on enhancing the driving experience. In recent years, with the global warming and people's attention to energy efficiency, the new car window film has become a new favourite in the market with its excellent heat insulation and energy-saving characteristics, and is leading the industry into a new stage of development. 
From the point of view of the principle of heat insulation, the new car window film adopts multi-layer nano optical film technology. The film body contains dozens or even hundreds of layers of different functions of nanoscale film, the thickness of each layer of film is only nano level. Among them, the metal oxide coating can effectively reflect the sun's infrared radiation, blocking a large amount of heat into the car. For example, in the hot summer, ordinary car windows will let a lot of heat into the car, resulting in a sharp rise in the temperature inside the car, while the new window film affixed to the vehicle, through the metal oxide coating of the reflective effect of the solar infrared radiation can be more than 60 per cent of the heat blocked in the car outside. At the same time, the heat-absorbing layer in the window film can absorb part of the heat through, and through a special heat dissipation mechanism will be emitted to the outside of the car, further reducing the temperature inside the car. 
In terms of energy saving effect, the new car window film is particularly outstanding. As it effectively blocks heat from entering the car, it greatly reduces the load on the car's air conditioner. In the past, under the hot weather, the car air conditioning needs to run at high load for a long time in order to maintain a comfortable temperature inside the car, which not only increases the fuel consumption, but also increases the pressure of the engine. After installing the new window film, the air conditioner does not need to run at full capacity to achieve the same cooling effect. According to relevant test data, during long-distance driving, the use of the new heat-insulating window film can reduce automotive fuel consumption by 8% - 12%, which will save a considerable amount of fuel costs for long-term car owners. At the same time, reducing the frequency of air-conditioning use also helps to extend the service life of the air-conditioning system and reduce maintenance costs. 
In addition to thermal insulation and energy saving, the new window film also offers significant improvements in other properties. In terms of UV protection, its UV blocking rate of up to 99% or more, can effectively protect the skin health of passengers in the car, to prevent skin sunburn, aging, while avoiding the interior of the car due to UV radiation and fading, cracking, and prolong the life of the interior. In terms of light transmittance, despite the multi-layer structure and strong heat insulation function, the new window film still maintains a good light transmittance effect, ensuring that the driver has a clear view and protecting driving safety. Even at night or in poorly lit environments, the window film will not affect the driver's vision. In addition, the new window film also has an excellent anti-glare function, which can effectively reduce direct sunlight and glare caused by the lights of the opposite vehicle, alleviate the driver's visual fatigue and improve driving safety. 
With the popularity of the new car window film, it has a profound impact on the automotive industry. On the one hand, it has prompted window film manufacturers to increase investment in research and development, and constantly explore new materials and technologies to enhance product performance and take advantage of competition in the market. On the other hand, it has also led to the development of the related installation service industry, professional window film installation technology training courses came into being, to train more technicians who are skilled in new window film installation techniques, to ensure the quality of window film installation, to provide consumers with a better service experience. 
In the future, with the continuous progress of technology, the new automotive window film is expected to achieve greater breakthroughs in thermal insulation and energy saving performance, and at the same time, combined with intelligent technology, to bring car owners a more intelligent, personalised driving experience. For example, there may be intelligent window films that can automatically adjust the light transmission rate and heat insulation effect according to the external light intensity, further enhancing the comfort and energy efficiency of the vehicle.
