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.

Abstract: In one embodiment, a multilayer structure may include a machine direction oriented (MDO) multilayer film, a first layer, and a sealant layer. The MDO multilayer film may include (i) a metal layer and (ii) an inner layer. The inner layer may include EVOH: PVOH: or 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. The first layer may include an interpolymer of ethylene and acry lic acid or methacrylic acid. The interpolymer may have a melt index (12) of 5 to 20 g/10 minutes. an acid content of 1 to 10 weight percent and a melting temperature of 90° C. to 100° C. The sealant layer may include 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.
