Beyond just looks, choosing between transparent and black & white PE film signifies different protection needs. Transparent film's core advantage is high clarity, allowing for visual inspection of the substrate underneath. This is ideal for stainless steel, aluminum, or high-gloss acrylics.
The core advantage of Black & White film is its light-blocking capability. It has a white outer side to reflect heat and a black inner side to block UV rays, protecting underlying materials from yellowing and aging. It's the preferred choice for plastic profiles and metal sheets stored outdoors. Blue film is often used in construction for its high visibility.
Choosing a color depends on the final product use, storage environment, and processing line requirements. Each color serves a specific defensive purpose.
