Abstract: Multilayered polymer films are configured so that successive constituent layer packets can be delaminated in continuous sheet form from the remaining film. The new films are compatible with known coextrusion manufacturing techniques, and can also be made without the use of adhesive layers between layer packets that are tailored to be individually peelable from the remainder of the film. Instead, combinations of polymer compositions are used to allow non-adhesive polymer layers to be combined in such a way that delamination of the film is likely to occur along a plurality of delamination surfaces corresponding to interfaces between particular pairs of layers for which the peel strength is reduced relative to the peel strength at other layer interfaces within the film. The absence of an adhesive between peelable layer packets results in the delamination being irreversible.

Abstract: Multilayered polymer films are configured so that successive layer packets can be delaminated in continuous sheet form from the remaining film. The films are compatible with known coextrusion manufacturing techniques, and can be made without adhesive layers between layer packets. The layer packets are individually peelable from the remainder of the film. Combinations of polymer compositions are used to allow non-adhesive polymer layers to be combined such that irreversible delamination of the film is likely to occur at interfaces between layer packet pairs. The films are post-formed, e.g. using heat and pressure, to deform the film from an initial flat or limp condition into a contoured shape that is self-supporting. The contoured shape may comprise regions of simple and/or complex curvature. Despite the permanent contoured shape, individual packets can still be successively peeled away to expose a fresh surface of the next layer packet, having the same contoured shape.

The films are compatible with known coextrusion manufacturing techniques, and can be made without adhesive layers between layer packets that are tailored to be individually peelable from the remainder of the film. Instead, combinations of polymer compositions are used to allow non-adhesive polymer layers to be combined such that irreversible delamination of the film is likely to occur at interfaces between layer packets pairs. Some of the polymer layers, including at least one embedded layer, comprise an antimicrobial agent, and these layers may be positioned at the front of each layer packet. After the antimicrobial layer of one layer packet has been used, the packet can be peeled away to expose a pristine antimicrobial layer of the next layer packet. The antimicrobial agent may be organic.

Abstract: An optical system for examining an optical characteristic of a test material at at least a first wavelength includes an elongated hollow structure elongated along a length thereof and having one or more walls extending along the length of the hollow structure and defining an elongated chamber therebetween configured to receive the test material. The elongated hollow structure includes at least a first light opening, such that for the at least the first wavelength, the one or more walls have an optical reflectance of greater than about 50% for incident angles of up to at least 40 degrees, and at least one of the at least the first light opening has an optical transmittance of greater than about 50% for at least one incident angle.

Abstract: This disclosure describes multilayer polymer films that are configured so that successive constituent layer packets may be delaminated in continuous sheet forms from the remaining film. This disclosure further describes compositions, materials, and methods for minimizing the likelihood of removing multiple layer packets together including by increasing the peel force between layer packets. In some embodiments, that the peel force becomes successively greater from the interface between the first layer packet and the second layer packet to the interface between the next to last ((n−1)th layer packet) and the last (nth layer packet).

Abstract: An optical system (200) that allows a viewer (10) to simultaneously see images created by an electronic display (20) as well as real world objects (30b) includes a reflective polarizer (41) as an image combiner for head-mounted displays and an absorptive polarizer (42) deployed in the same combiner to reduce glare by minimizing ambient reflections from the reflective polarizer. To prevent the absorptive polarizer (42) from blocking linearly polarized light sources from being transmitted through the combiner, a weak absorptive polarizer is provided to allow transmission of polarized sources while still minimizing glare.

Abstract: Multi-layer films, and processes to make the films, that enable the delivery of a substrate featuring a peelable thin layer of low haze, amorphous, isotropic film with the desired properties of high modulus, high usage temperature, UV blockage, and toughness The films are made using a co-extrusion, co-orientation and annealing process to enable the delivery of a thin isotropic, UV blocking layer on top of a release layer and support substrate. These film constructions can be kept together during additional processing steps such as coating and converting. The release and dimensionally stable substrate layer can be easily removed once processing steps are completed.

Abstract: Barrier assemblies including ultrathin barrier laminates and methods of making the barrier assemblies are provided. A barrier assembly includes a thermoplastic polymer skin layer having opposite first and second major surfaces, and a barrier stack coated on the first major surface of the thermoplastic polymer skin layer to form an integral protective layer having a thickness no greater than about 0.5 mil (about 12.7 microns). The removable carrier film has a major surface releasably attached to the second major surface of the thermoplastic polymer skin layer. In some cases, the removal of the carrier film results in ultrathin barrier laminates.
