Feature
Silica dioxide is a commonly used material in the production of PET back print backlit film. It is added to the film formulation
to enhance its optical properties and improve its light diffusion capabilities.
PET (polyethylene terephthalate) is a durable and transparent plastic material that is commonly used in various applications,
including backlit films. When used in backlit film, PET provides a smooth and even surface for printing graphics or text.
However, PET alone may not provide the desired level of light diffusion for backlit applications. This is where silica dioxide
comes into play. Silica dioxide, also known as silica or silicon dioxide, is a white, powdery substance that is added to the
PET film formulation.
The addition of silica dioxide helps to scatter and diffuse light evenly across the film's surface. This allows for a more uniform
distribution of light and enhances the visibility and vibrancy of the printed graphics or text when illuminated from behind.
Silica dioxide also helps to improve the film's optical properties by reducing glare and reflection. This ensures that the printed
content remains clear and legible, even in bright lighting conditions.
In addition to its light diffusion and optical properties, silica dioxide also provides other benefits to PET back print backlit film.
It enhances the film's mechanical strength and dimensional stability, making it more resistant to tearing or warping.
Overall, the addition of silica dioxide to PET back print backlit film is essential for achieving high-quality and visually appealing
results. It enhances the film's light diffusion capabilities, improves its optical properties, and enhances its overall durability.
