A fog-resistant polyolefin packaging film is prepared by producing a film of a formulation comprising ethylene or a polypropylene polymer, having incorporated therein and an antifog agent comprising: a) a C8 or higher ester, diester, and/or triester of a C2 to C8 polyhydric alcohol; and b) a mono-or dialkoxylated C10 or higher amine. In a preferred embodiment, said film further comprises c) an alkoxylated alkylphenol or derivatives thereof. Said antifog agent is present in an amount which imparts antifog resistance performance to said film in about less than an hour.
