A multilayer polymer film for use in packaging, particularly food packaging, and packaging made from the multilayer film, are disclosed, along with methods of manufacture of the multilayer film and the packaging. In preferred embodiments, the polymer film comprises an outer layer comprising machine direction oriented high-density polyethylene, an intermediate layer comprising adhesive and optionally ink, and an inner layer comprising high-density polyethylene, metallocene linear low-density polyethylene, and a plastomer. The inner or outer layer can be coated to lower the water vapor and oxygen transmission rates. In preferred embodiments, the layers are laminated to form the multilayer film. The multilayer film can be used to produce food packaging such as heat-sealable bags or pouches. Packaging made from the film is suitable for hot filling, and in contrast to packaging materials known in the art for hot filling, is fully recyclable.
