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: Optical films having a curved shaped and methods of shaping optical films are described. A method of shaping an optical film includes the steps of disposing the optical film adjacent first and second rollers spaced apart along a first direction, securing opposing first and second ends of the optical film, providing a curved mold surface, and shaping the optical film by contacting the optical film with the curved mold surface while stretching the optical film along the first direction and keeping a threshold distance between closest points on the optical film contacting the first roller and contacting the curved mold surface less than the width of the optical film to reduce buckling of the optical film.

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: A feedblock including a first packet creator that forms a first packet including a first plurality of polymeric layers, the first plurality of layers including at least four first individual polymeric layers; and a second packet creator that forms a second packet including a second plurality of polymeric layers, the second plurality of layers including at least four second individual polymeric layers, wherein the first and second packet creators are configured such that, for each packet creator, respective individual polymeric layers of the plurality of polymeric layers are formed at approximately the same time. The feedblock may include a packet combiner that receives and combines the first and second primary packets to form a multilayer stream. In some examples, at least one of the first and second primary packets may be spread in the cross-web direction prior to being combined with one another.

Abstract: A polymeric film has an orthogonal length, width and thickness. The polymeric film includes first and second substrates spaced apart along the thickness and a plurality of crumpled elements extending between the first and second substrates and along the length. The crumpled elements are substantially coextensive with the first and second substrates along the length and are spaced apart along the width.

IPC: G02B5/28
Abstract: A film includes a first layer having a substantially constant thickness. The first layer extends substantially uniformly along a length direction of the first layer and includes adjacent continuous first and second portions extending along the length direction. Each of the first and second portions includes a substantially constant thickness portion extending to an edge of the first layer along a width direction of the first layer, and a tapering portion adjacent the substantially constant thickness portion and having a thickness tapering in the width direction to a minimum thickness at an end of the tapering portion opposite the substantially constant thickness portion. The minimum thickness can be less than 20% of a thickness of the substantially constant thickness portion. The tapering portions of the first and second portions can have respective first and second major surfaces substantially conforming to one another.

Abstract: A polymeric film has an orthogonal length and width. The polymeric film includes a substrate and a plurality of fins extending away from the substrate and substantially coextensive with the substrate along the length. The fins are arranged across the width. Each fin in at least a majority of the fins includes a first portion extending from the substrate to a tip of the fin opposite the substrate; and a second portion extending from the tip of the fin toward or to the substrate. The second portion is attached to the first portion proximate the tip and separated from the first portion proximate the substrate along at least a portion of the length. The first and second portions have different respective first and second compositions.
