A multilayer film suitable for sealing containers such as used for food packaging, and methods of making the film, are described. The film is particularly suitable for sealing containers made from polylactic acid (PLA). The multilayer film includes a) a substrate that includes a polymeric base layer; and b) on the substrate, a heatseal layer containing a PLA homopolymer or copolymer. The heatseallayer further includes dispersed therein an adhesion promoter, or alternatively the substrate further includes the adhesion promoter in a layer on a surface of the polymeric base layer between and adjacent the base layer and the heatseal layer. An antifog agent may also be included in the heatseal layer or on the surface of the heatseal layer opposite the substrate.
