  • Patent number: 10619020
    Abstract: Embodiments of monolayer and multilayer films which provide an improved matte surface are disclosed. The monolayer film or an outer layer of the multilayer films comprise greater than 50% by weight of a first polyethylene having a density of at least 0.935 g/cm3 and a melt index (I2) of 0.9 g/10 minutes or less, and less than 50% by weight of a second polyethylene having a density less 0.935 g/cm3 and a melt index (I2) of 20 g/10 minutes or less, wherein the film exhibits an external gloss of less than 20 units when measured at 45 according to ASTM D2457 and a haze greater than 60% when measured according to ASTM D1003.
    Type: Grant

  • Patent number: 9676172
    Abstract: The present invention relates to film structure suitable for use in stand up pouches comprising all polyethylene material. The film structure can be a monolayer film or a multilayer film structure having specific requirements for each layer. The combination results in a film structure having adequate stiffness to function as a stand-up pouch while also providing acceptable water vapor transmission rates and good tear resistance. Such films have improved sustainability characteristics as they should permit down-gauging of the films and, can more easily be recycled, at least for the preferred embodiment comprising only polyethylene resins.
