With the rapid development of LED lighting technology, the market demand for high-efficiency reflective materials is becoming increasingly urgent. Recently, a white reflective PET film designed specifically for LED lighting has attracted industry attention. Its excellent optical performance and wide application scenarios have injected new impetus into the upgrading of the lighting industry.

High reflectivity improves lighting efficiency

The white reflective PET film is copolymerized with dimethyl terephthalate (DMT) and ethylene glycol slices, and a dense crystal structure is formed through a biaxial stretching process, with a reflectivity of more than 88%. Compared with traditional reflective materials, it can more effectively concentrate light from the light source and reduce light loss. Actual measured data shows that after the film is applied to LED lamps, the light efficiency is increased by about 20%, significantly enhancing the brightness and uniformity of the lighting.

Core technology breaks through the bottleneck of the industry

The technical team adds special polyester masterbatch to give the film excellent heat resistance (temperature range -40℃ to 120℃) and dimensional stability, ensuring that it will not deform or yellow under long-term light. Its surface wetting tension reaches 38 dynes/cm, supports precision die-cutting and hot pressing, and is suitable for complex lamp structures. According to third-party testing, the film's impact resistance is 20% higher than that of ordinary PVC materials, effectively resisting accidental collisions during transportation and installation.

Multi-scenario empowering green lighting

In the field of commercial lighting, the film is widely used in LED spotlights and light strips in art galleries, shopping malls and other places. Its low light transmittance (<2%) can completely block the glare of the lamp beads and create a comfortable light environment. An electronics manufacturer reported that after using the film, the energy consumption of its ultra-thin light box was reduced by 15%, and due to the recyclable nature of the film material, it complies with the EU RoHS environmental protection standards. In addition, in the field of automotive electronics, the film is used as a key material for the instrument panel backlight module, helping to achieve clearer display and lower power consumption.

Innovative technology expands the application boundaries

Manufacturers provide a variety of thickness specifications from 0.05-0.3mm, supporting coil slitting and sheet customization. In a recent case, a smart lighting company used 0.188mm ultra-thin film to make a bendable reflective cup, which reduced the thickness of the lamp by 40% while maintaining a 90% reflectivity. This flexible feature also provides possibilities for innovative designs such as curved lighting and special-shaped light strips.

As the global LED lighting penetration rate continues to increase, white reflective PET film is becoming a key puzzle piece for industrial upgrading with its technological advantages and environmental protection characteristics. In the future, with the advancement of material science, its reflectivity is expected to break through the 90% mark, further promoting the green lighting revolution.
