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.

Abstract: A multilayer film comprises first, second, and third layers. The first layer comprises at least one aromatic polyester, and has a loss modulus at 1 hertz and 25° C. of at least 70 megapascals. The second layer is thermoplastic and has a loss modulus at 1 hertz and 25° C. of less than or equal to 60 megapascals and comprises a thermoplastic elastomer and a polyamide. The third layer contacts the second layer opposite the first layer and has a loss modulus at 1 hertz and 25° C. of at least 70 megapascals. The second layer is sandwiched between the first and third layers. A method of making the multilayer film by coextrusion is also disclosed.

Abstract: Multi-layer optical films that can be utilized as polarizer or mirror films and can be incorporated into optical stacks. The optical film includes a plurality of alternating polymeric first and second interference layers numbering greater than 50 and disposed between, and integrally formed with, first and second skin layers, each of the first and second interference layers has an average thickness less than 250 nm. The first and second interference layers and the first and second skin layers are compositions that include polyester.

Abstract: The present method comprises providing a flexible web substrate (e.g., polymeric flexible web substrates) that forms at least part of a component of a device, coating so as to wet-out on and cover all or a substantial portion of a major surface on one side or both sides of the flexible web substrate with flowable polymeric material, while the flexible web substrate is moving in a down-web direction, and solidifying the polymeric material so as to form one cleaning layer on the major surface of one side or both sides of the flexible web substrate. The present invention can be utilized in a continuous in-line manufacturing process. In applications of the present invention where the flexible web substrate will not form a component of a device, the present invention broadly provides a method for cleaning particles from a flexible web of indefinite length. Each cleaning layer forms a substantially adhesive bond to the major surface that is readily removable without damaging or leaving a substantial residue of cleaning layer material on the major surface. A substantial number of the particles that were on this major surface are captured by and removable with the cleaning layer.

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: 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.
