Films with this capability allow most UV rays of 300-380nm to pass through. The ultraviolet transmission of this band can better simulate the outdoor growing environment, and it is recommended for crops with coloring requirements, such as two-color, multi-color roses, berries and red vegetables.

Allowing short-wavelength ultraviolet light to pass through has the following benefits for berries: early market, shorter segment spacing, larger fruits, good color (strawberries are more colorful, reducing the "white background" phenomenon), more sugar and nutrients. Uv open film is helpful for the color formation of two-color roses and red-leaf vegetables. However, this film should be used with caution in strong light and high altitude areas to avoid causing burns to crops.
