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.

Cellulose acetate films having excellent optical properties are disclosed. The films are made from cellulose acetate and a plasticizer. A solvent cast precursor film is initially formed and then subjected to high temperatures and pressures for improving at least one optical property.

A material for a hot melt extrusion method contains at least a cellulose derivative and an additive. The cellulose derivative is cellulose acetate propionate and when a degree of substitution of an acetyl group is X and a degree of substitution of a propionyl group is Y, the cellulose derivative satisfies the following Expression (1) and Expression (2); and the additive contains a plasticizer and a compound A containing a partial structure having a NICS value in the range of −14 or more and −10 or less,

[00001]$\begin{array}{cc}2.0\le X+Y\le 3.0& \mathrm{Expression}\left(1\right)\\ 0.5\le Y\le 2.6.& \mathrm{Expression}\left(2\right)\end{array}$

The present disclosure is directed to recyclable lined molded fiber articles (e.g., bowls) that provide the necessary performance characteristics for storing frozen and refrigerated foods (acceptable oil resistance, water resistance, and water vapor barrier). The disclosed articles and methods for manufacturing such articles include bonding a thermoformable cellulose-based acetate film to a molded bagasse fiber article to form an impervious liner.

Solution casting a nanostructure. Preparing a template by ablating nanoholes in a substrate using single-femtosecond laser machining. Replicating the nanoholes by applying a solution of a polymer and a solvent into the template. After the solvent has substantially dissipated, removing the replica from the substrate.

An object of the present invention is to provide a cellulose acetate composition with excellent biodegradability and water solubility, and excellent thermoformability. A cellulose acetate composition containing: a cellulose acetate having a degree of acetyl substitution of 0.4 or greater and less than 1.4; and at least one type of glycerin ester-based plasticizer selected from the group consisting of monoacetin and diacetin, wherein a content of the glycerin ester-based plasticizer is 3 parts by weight or greater per 100 parts by weight of the total amount of the cellulose acetate and the glycerin ester-based plasticizer.

A composition for an enteric hard capsule by taking advantage of conventionally unknown thermal gelation characteristics of a neutralized aqueous solution of an enteric polymer, so as to obtain an enteric capsule having sufficient water and acid resistances. More specifically, the composition has hypromellose acetate succinate having a molar substitution with an acetyl group per anhydroglucose unit of 0.6 to 0.8 and a ratio of the molar substitution with an acetyl group to a molar substitution with a succinyl group per anhydroglucose unit of 2.0 to 4.0, a neutralizer, and water method produces an enteric hard capsule having the steps of: immersing a core pin heated at 50 to 80° C. in the composition, taking the immersed core pin out of the composition, and drying a gel layer of the hypromellose acetate succinate formed on the taken-out core pin.

A resin composition includes: a cellulose acetate propionate and cellulose fibers in which a part or all of primary hydroxyl groups of glucose moieties are oxidized into a carboxylic acid, the cellulose fibers having an average fiber diameter of 1 to 8 nm.

A method is described for making a retort container having one or two metal ends. A heat-sealable material is present on one or both of the container side wall and the/each metal end. The/each metal end is seamed onto the container body, and the resulting container assembly is conveyed on a conveyor adjacent to an induction sealing head and then adjacent to a cooling device. A pressure belt engages the upper end of the container assembly to keep the metal end from coming off the container body during the induction heating and cooling processes.
