    Abstract: According to one embodiment of the present disclosure, a multilayer structure may comprise a machine direction oriented (MDO) multilayer film, a first layer, and a sealant layer. The a MDO multilayer film may comprise (i) a metal layer and (ii) an inner layer in adhering contact with the metal layer. The inner layer may comprise ethylene vinyl alcohol; polyvinyl alcohol; or may comprise a blend of polyethylene and an interpolymer of ethylene and methyl acrylate, ethyl acrylate, or carboxylic acid. The first layer may be extruded onto the metal layer of the machine direction oriented multilayer film. The first layer may comprise an anhydride grafted polyethylene. The sealant layer may be in adhering contact with the first layer. The sealant layer may comprise a polyethylene having a melt index (I2) of 3 to 30 g/10 minutes and a heat seal initiation temperature of 95° C. or less.
