We get many requests for clear, fire retardant plastic sheeting, or clear anti-static fire retardant plastic sheeting. What people need to understand is the additives that need to be added to the polyethylene that make polyethylene fire retardant turns the plastic into a whitish color. When the additives are added to make it anti-static, it makes the film even whiter. There is no getting around this.
We have 6 mil Anti-Static Fire Retardant film on the shelf, but it is fairly opaque, definitely not clear.
