Abstract: Provided is the use of a film of a cellulose ester as a barrier against moisture and oil. The cellulose ester has free hydroxyl groups and ester substituents. The ester substituents are each individually selected from C1 to C6 alkyl ester groups. The free hydroxyl groups are present in an amount in the range 15 % to 40 mol%. The film is useful as a barrier layer for food packaging. Also provided is a composition comprising the cellulose ester and a further film-forming material, a packaging material comprising a film of the composition, and a method for manufacturing the packaging material.

Abstract: Example biodegradable tubular members and methods of producing biodegradable tubular members are described. A biodegradable product includes an elongated tubular member. The elongated tubular member includes one or more cellulose esters and a plurality of pores in the tubular member. The plurality of pores are sized and structured in the elongated tubular member to allow permeation or infiltration of at least one of water or bacteria into at least a portion of the plurality of pores and promote biodegradability of the elongated tubular member.

Abstract: A composition comprising a continuous thermoplastic polymer matrix having a melting point greater than 110 °C and, distributed within the matrix, particles of hydrophilic natural fiber material having a sieved size of less than 1.0 mm, the weight ratio of the thermoplastic polymer to the wood particles being from 99:1 to 35:65. An improvement in biodegradability of biopolymers, such as PLA, can be achieved. On the other hand, the addition of wood fibers enhances the material's ability to resist thermal deformation. The present compositions can be used for manufacturing hollow structures, by injection blow molding, of bottles with a wall thickness between 0.1 mm and 5 mm, in particular from 0.3 to 1 mm or continuous extruded products with a wall thickness from0.3mm to 1.5 mm.

Abstract: Regioselectively substituted cellulose esters having a plurality of aryl-acyl substituents and a plurality of alkyl-acyl substituents are disclosed along with methods for making the same. Such cellulose esters may be suitable for use in optical films, such as optical films having certain Nz values, -A optical films, and/or +C optical films. Optical films prepared employing such cellulose esters have a variety of commercial applications, such as, for example, as compensation films in liquid crystal displays and/or waveplates in creating circular polarized light used in 3-D technology.
