A multilayer film comprises: a first layer comprising a first homogeneous ethylene/alpha-olefin copolymer; a second layer comprising a polyolefin; and a third layer comprising a second homogeneous ethylene/aipha-olefin copolymer. The second layer is between the first layer and the third layer, the second layer is chemically different from the first layer and the third layer, and the multilayer film has an O.sub.2 -transmission rate of from about 500 to 50,000 cc/m.sup.2 /24 hr STP. One outer layer of the film comprises an antifog agent on the outer surface thereof. Also disclosed is a package made from the film.
