Double Poly Film - Opacity of Double Poly Film Bulletin

Opacity of Double Poly
The table below is intended as an aid in the selection process when using two partially opaque films on the same structure.

Example (refer to the table):

• Film A - opacity = 55%
• Film B - opacity = 70%

Opacity of two films combined = 77%
It does not matter whether film A or B is the outside film.

Note that the table contains some film opacities that we currently do not offer and are only listed for informational
purposes. The results in the table were obtained from actual film test data.
