Food packaging and horticultural films used with water-containing products often fog over on their inner surface due to the condensation of tiny droplets of moisture.
Droplets are particularly undesirable in greenhouse films, where good light transmission is essential for crop growth.

Fogging on
plastics films is really not all that different than the
fog that forms outside; it’s just that, on a plastic
film, fog forms on a convenient hydrophobic
surface—namely, the film.
Spraying a coating on a film’s surface requires
an investment in capital equipment and use of
a secondary process in a film manufacturing
line.
It must not
affect the optical properties of the film.

Versaflex™ CF Low Adhesive Build-up TPE
for Protective Film Tack Layer
Protective films guard the surface of finished goods
from initial fabrication through assembly, shipment,
storage, and installation.
Versaflex™ CF 6668 low adhesion build-up TPE for
protective film meets that need.
It also provides low unwinding force to
improve efficiency when pasting film.
