Abstract: This disclosure provides compositions and methods for a film, which may include a base film and a coating layer on the base film, wherein the coating layer has a surface energy of at least 30 dynes/cm and consists essentially of nylon, polyester, ethylene vinyl alcohol-based copolymer, polyvinyl alcohol-based polyethylene terephthalate, polyvinylchloride, acrylate-based polymers, methacrylate-based polymers, polyurethane, polyalkylimine, acid-modified polyolefins, polyetherester-amide block copolymer, and combinations thereof. Further, the film may include a metal oxide layer on the coating layer, wherein the metal oxide layer has an optical density of equal to or less than 0.5 and a thickness from 0.1 nm through 100 nm. Further still, the film has an oxygen transmission rate of less than 4 cm3/m2/day at 23° C. and 0% relative humidity, a water vapor transmission rate of less than 4 g/m2/day at 38° C. and 90% relative humidity, and a thickness of 5 ?m through 50 ?m.

Abstract: This disclosure provides compositions, films, labels, structures and methods that may include a substrate having a first side and a second side, wherein the first side comprises a skin layer comprising at least 50 wt. % of high-density polyethylene. Further, the compositions may include a coating on the skin layer, wherein the coating comprises a topcoat and a primer, wherein the topcoat consists of: (i) at least 50 wt. % high-density polyethylene and one or more polyethylene polymers in water; (ii) wax, silicone or combination thereof; and (iii) optionally additives, whereupon imaging the composition by a thermal print head at a temperature of 300° C. or less results in no or negligible solvent-penetrability beneath the skin layer.

Abstract: This disclosure provides methods, systems and devices that may be used to measure, calculate, and orient a device such as a drill bit in a downhole environment. To that end, disclosed are fiber optic gyroscopes, wherein the fiber optic gyroscopes comprise elliptical fiber optic cable coils in a mutually orthogonal arrangement that is tilted relative to a length of a supporting shaft, e.g., tube. Light travels in opposite directions within each of the elliptical fiber optic cable coils, and, subsequently, sensors detect differences in time for each light path of the light that traveled in opposite directions within each one of the elliptical fiber optic cable coils. The elliptical nature of the fiber optic cable coils minimizes the cross-sectional area of the mutually orthogonal arrangement, and thereby makes it well-suited for use in downhole environments where space is at a premium. This disclosure also may provide an inertial measurement unit.

In one example embodiment, disclosed is a structure and composition, which includes a printable coating receptive to electrophotographic ink, an optionally oriented film having a coating side and a laminating side, wherein the printable coating is applied to the coating side, and a substrate dry-laminated to the laminating side.

Abstract: Disclosed is a multilayered film that includes a core layer that includes one or more polymers, wherein the core has a first side and a second side and is optionally oriented. Further, the multilayered film includes a sealing layer comprising a primer and a sealing coating, wherein the primer has a primer coating weight from 0.05 to 0.5 g/m2 and is located between the first side of the core and a first side of the sealing coating, wherein the sealing coating has a sealing coating weight from 0.5 to 20.0 g/m2, wherein the multilayered film has a seal strength of at least 1 kg/in at 120° C. In various embodiments, the films showed outstanding seal strength, hot tack for both clear and white films over a broad temperature range, seal integrity under the Skye test, low blocking, and other desirable performance metrics.

Abstract: Disclosed herein is a coated flexible oriented polypropylene film having three or more layers comprising a core layer of polypropylene; a sealing layer; a metal layer opposite the sealing layer, thereby sandwiching the core; and a printable coating adhered to the metal layer, thereby sandwiching the metal layer between the core layer and printable coating; wherein the printable coating comprises at least one primer layer of an ethylene acrylic acid-based copolymer and/or ethylene alkyl ester copolymer and at least one print layer comprising an acrylic styrene copolymer.
