  • Publication number: 20240367416
    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.

  • Publication number: 20240336044
    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.

  • Publication number: 20240092066
    Abstract: The present disclosure provides for a machine direction oriented polyethylene (MDO-PE) film, a laminate comprising the MDO-PE film and a method of forming the MDO-PE film. The MDO-PE film includes a core layer comprising a first ethylene-based polymer a skin layer comprising a second ethylene-based polymer and a sub-skin layer in-between and in contact with the core layer and the skin layer. Each value for the density, peak melting point and percent crystallinity by weight increases from the core layer to the sub-skin layer and from the sub-skin layer to the skin layer. The MDO-PE film further includes predetermined values for a ratio of the percent crystallinity by weight of the core layer to the skin layer and a ratio of the peak melting point of the core layer to the skin layer. The MDO-PE film can be useful in food package, among other areas.
