The term "fogging" refers to the condensation of water vapor on a plastic film's surface. This results in the formation of water droplets. In food packaging films the droplets makes the content less visible and may deteriorate the quality of the packed food product. In agricultural applications as greenhouses, fogging will affect the transmittance of light, causes burns of the crops by the lens effect of the droplets, and a continuous water drip. Typical Polyolefins are very hydrophobic. Water on a film surface will cause the formation of droplets (high contact angle: no wetting or spreading of the water over the surface).
