  • Patent number: 12179396
    Abstract: The present disclosure provides a process. In an embodiment, the process includes providing pellets of a regrind material. The regrind material is a post-consumer recycle multilayer film (PCR multilayer film) having at least three layers. The PCR multilayer film is composed of (i) a polyethylene layer, (ii) a polyamide layer, and (iii) a tie layer. The tie layer is composed of maleic anhydride grafted substantially linear ethylene polymer (MAH-g-SLEP) having a Mw/Mn from 1.5 to less than 3.5 and a melt index from 0.5 g/10 min to less than 25 g/10 min. The process includes extruding the pellets to form an extrudate, molding the extrudate, and forming, with the extrudate, a molded article having a surface. The surface of the molded article has a surface roughness value, Sa, less than 1000 nm and a root mean square roughness value, Sq, less than 1400 nm.

  • Patent number: 11203193
    Abstract: Embodiments of a laminate structure for use in flexible packaging comprise a sealant film comprising ethylene-based polymer, and a multilayer polyethylene print film laminated to the sealant film. The print film comprises at least 3 layers and has an overall thickness from 15 to 30 ?m. The print film comprises a middle layer, an inner layer disposed between sealant film and the middle layer, and an outer layer, wherein the middle layer comprises at least 90% by weight high density polyethylene (HDPE) polymer having a density from 0.950 to 0.965 g/cc. The inner layer and the outer layer comprise linear low density polyethylene (LLDPE) having a density from 0.925 to 0.965 g/cc. The laminate structure yields desired optical and mechanical properties coupled with recyclability and improved printing efficiency, while maintaining these low thicknesses for the print film.

  • Publication number: 20210331845
    Abstract: Embodiments of laminate structures for flexible packaging comprise a print film comprising ethylene-based polymer, a sealant film laminated to the print film, wherein the sealant film comprising at least 3 layers and has an overall thickness from 15 to 30 ?m. The sealant film comprises a middle layer, an outer layer, and an inner layer disposed between the print film and the middle layer. The inner layer comprises an ethylene interpolymer having a density from 0.910 to 0.925 g/cc and a melt index (I2) from 0.5 to 5 g/10 min, and at least one of the inner layer, the middle layer, and the outer layer comprise a first composition comprising at least one ethylene based polymer, wherein the first composition comprises a Molecular Weighted Comonomer Distribution Index (MWCDI) value greater than 0.9, and a melt index ratio (I10/I2) that meets the equation: I10I2?7.0-log (I2).

  • Patent number: 9836357
    Abstract: The disclosed computer-implemented method for backing up heterogeneous virtual environments may include (1) identifying a request to back up a virtual machine executing on a host system, (2) creating a storage map of a virtual storage environment of the virtual machine by (a) identifying, from the host system, a virtual disk file that stores data for the virtual machine and (b) identifying, from a guest system operating within the virtual machine, one or more virtual storage devices that store data for the virtual machine, and (3) creating a unified backup of the virtual machine based on the storage map of the virtual storage environment by coordinating a backup operation of the virtual disk file with a backup operation of the virtual storage device. Various other methods, systems, and computer-readable media are also disclosed.
