Abstract: A method and system for processing a heated flexible sheet, with oppositely facing surfaces, that is advanced in a processing path. A first cooling roll has a first peripheral surface for contacting one of the sheet surfaces. A second cooling roll has a second peripheral surface for contacting the other sheet surface.

Abstract: Smoking articles have a mouth end portion that includes a central filter plug having an outer surface. The mouth end portion further includes a peripheral region disposed about the outer surface of the central filter plug. The peripheral region may include one or more channels through which smoke may flow. The smoking article includes an exterior wrap that is disposed about the peripheral region of the mouth end filter portion. The permeability of smoke through the peripheral region is five times or more greater than the permeability of smoke through the central filter plug. By increasing the permeability of smoke around the central filter plug, less smoke travels through the central filter plug in the mouth end portion and less staining of the mouth end of the central filter plug results.

Abstract: Anti-fog compositions comprising a primary film having opposing major planar surfaces and a central coplanar region, and processes for making such anti-fog compositions. The central coplanar region is disposed between the opposing major planar surfaces. The primary film comprises cellulose acetate, plasticizer, and an anti-blocking agent. The anti-blocking agent has an average particle size ranging from 0.02 microns to 6 microns. The cellulose acetate has a degree of substitution that increases from the opposing major planar surfaces toward the central coplanar region or that is substantially constant throughout the thickness of the composition. The composition is formed by saponifying a precursor film to improve hydrophilicity.

Abstract: Cellulose diester films that include a cellulose diester; a plasticizer; a colorant; and an opacity additive may be useful for playing cards. In some instances, forming cellulose diester films may include preparing a dope that comprises a cellulose diester, a plasticizer, and a solvent; introducing a colorant and an opacity additive into the dope to yield a casting dope; and casting the casting dope into a cellulose diester film. Playing cards may then be produced by methods including, for example, cutting the cellulose diester film and printing on the cellulose diester film.

Abstract: There is provided a cellulose ester film comprising at least one plasticizer and satisfying the following expressions (1) to (5); |Re|?5 nm (1); 50 nm<Rth<300 nm (2); 25 ?m?d?65 ?m (3); 1×10?3?Rth/d?4×10?3 (4); 3.8 GPa<E?<5.0 GPa (5); wherein Re represents a retardation value in an in-plane direction; Rth represents a retardation value in a thickness direction; d represents a film thickness; and E? represents an elastic modulus of the film.

Abstract: Provided is a cellulose acylate film. More particularly, the present invention relates to a cellulose acylate film having a low light scattering efficiency (haze).

Abstract: A bioplastic composition may contain certain biodegradable and renewable components. In some examples, the bioplastic composition includes at least one kind of aquatic macrophyte biomass, which may contain a native composition of protein and carbohydrates, in a blend with one or more types of biodegradable or durable thermoplastic polymers. The aquatic macrophyte composition may provide a balance of both polymeric and reinforcing properties to the blended bioplastic not typically exhibited by terrestrial feedstock such as soy meal or corn starch. Such a bioplastic composition may be formed into molded articles using extrusion, injection molding, compression molding, or the like.

Abstract: The present invention provides a process for optimizing the fragrance of a scented cellulosic.

Abstract: Protective films for plasma displays, spectacles or especially polarizers (for example based on cellulose triacetate) including particular plasticizers as a constituent of imaging devices of liquid-crystal type or of spectacles, their production and use, and liquid-crystal display devices and film polarizers producible with them, and also further subject matter of the invention specified in the description, are particularly suitable for thin films and have advantageous properties, for example low water vapor permeability. The plasticizers used are one or more of the formula (I) in which the radicals are each as defined in the rest of the disclosure and are branched-chain alkyl radicals having 9 or 10 carbon atoms, and advantageously one or more further plasticizers.

Abstract: The present inventions relate to cellulose esters having low hydroxyl content for use in optical applications, such as liquid crystal display (LCD) films. Films with low hydroxyl levels and a given ratio of non-acetyl ester to hydroxyl level have low intrinsic birefringence. These films can be cast, molded, or otherwise oriented without an appreciable birefringence or optical distortion (i.e. retardation). These films are useful in polarizer, protective, and compensator films and in molded optical parts, such as lenses. The resins of the present inventions can also be made to have “+C plate” behavior either by melt or solvent based processing, which is uncharacteristic of cellulose esters. Such +C behavior allows films having unique compensatory behavior. Other embodiments of the invention relate to methods of melt casting films while minimizing birefringence. Another embodiment of the invention is directed to films made from the cellulose esters described herein further comprising a plasticizer.
