Abstract:
A lidstock material suitable for sealing plastic containers that are retorted at elevated temperatures to sterilize their contents. The lidstock material comprises a substrate joined to a film comprising a mixture of a butene-1 polymer; high density polyethylene; polypropylene; and a powdered filler. The lidstock material is heat sealable, peelable, and retains high burst strength both during and after retorting at elevated temperatures.
Abstract:
A directly illuminated display unit has a display panel and one or more light sources disposed behind the display panel. A diffuser is disposed between the light source unit and the display panel and a light diverting layer is disposed between the one or more light sources and the diffuser. The light diverting layer has light diverting members on a first side of the light diverting layer facing the diffuser. Surfaces of the light diverting members are disposed at more than one angle relative to a normal to the light diverting layer and also include one or more sharp changes of surface slope. The light diverting members spread the illumination light so as to be more uniform. Different light diverting members can have different apex angles. Also, different sides of a light diverting member can have best fit centers of curvature that are non-coincident.
Abstract:
A peelable and heat sealable lidstock material comprises a metal or polymer substrate laminated with a film comprising a mixture of a butene-1 and ethylene copolymer, an ethylene homopolymer or copolymer, an inorganic filler and optionally, a propylene homopolymer or copolymer. The filler makes up at least about 18 wt. % of the mixture and is preferably talc having an average particle size of about 1-2 microns and a carboxylic acid surface coating.

Abstract:
Articles produced according to the present disclosure include a first film having a structured surface and a second film having a structured surface. The structured surface of the first film is releaseably mated with the structured surface of the second film. In some exemplary embodiments, such articles may be optical bodies including first and second optical films having structured surfaces. Methods of making such articles, which may be optical bodies, are also disclosed.
Abstract:
A display includes an optical film that has a surface structure, such as a prismatically structured surface for increasing the brightness of the display. The structured surface is bonded to an opposing surface of a second film using a layer of adhesive, by penetrating the structured surface into the adhesive layer to a depth less than a feature height of the structured surface. The bonded film structure provides additional strength to the films and reduces the possibility of film damage during display assembly.
Abstract:
The present invention is a light directing construction for use in a display apparatus. The light directing construction includes a light directing film that has a prismatic structure having two sides, where one side includes saw tooth formations having tilted surfaces, and a metal coating on the side of the prismatic substrate having the saw-tooth formations. A corrosion-resistant feature is provided on the light directing construction to minimize the effects of corrosion experienced in salt atmospheres. In a first embodiment of the invention, the light directing construction includes an intermediate layer positioned between the light directing film and the metal coating. In a second embodiment of the invention, a peripheral polymeric coating is provided on the light directing constriction. This peripheral coating can be formed with a laser.
Abstract:
In one embodiment, the present invention is a polymeric composition, in pellet form, which comprises a vinyldene chloride interpolymer, and a friction reducing polymer (FRP) in an amount of from about 0.1 to about 40 weight percent, said weight percent being based on the total weight of the polymeric composition. The FRP is selected to selected to lower the frictional coefficient and the mechanical energy to extrude of the polymeric composition. In another embodiment, the present invention is a polymeric composition, in either power or pellet form, possessing improved extrudability, composition comprises a vinylidene chloride interpolymer in an amount of from about 55 to about 99.85 weight percent, a FRP in an amount from about 0.1 to about 40 weight percent, and a salt of an acid in an amount of between about 0.05 and about 5 weight percent, said weight percents being based on the total weight of the polymeric composition.
