An aqueous composition for making dip-molded comestible hard capsules comprising a film forming capsule base material and one or more colorants each consisting of a hydrophilic coloring foodstuff concentrate.

Disclosed is a co-extruded multi-layered cellulose-based film, which comprises at least a first film layer A comprising at least one first cellulose-based polymer and at least one second polymer. The film further comprises at least one sealing layer B being an outer layer and/or a middle layer of said film, and at least one slip additive. Further, the film is produced by a film extrusion process. Disclosed are also packaging materials comprising the film and a method related thereto.

The invention discloses a manufacturing method of a speaker vibrating diaphragm by controlling a ratio of fiber materials, the method comprising the steps of: (A) fabric provision: providing a fabric interwoven by a plurality of warps and a plurality of wefts; (B) impregnation: impregnating the fabric in a resin solution; (C) drying: drying the fabric impregnated with resin solution; (D) formation: pressing the dried resin-impregnating fabric to form a predetermined shape; and (E) cutting: cutting the formed speaker vibrating diaphragm from the fabric. Each of the plurality of warps and each of the plurality of wefts of the fabric has an individual yarn count and material composition. By controlling a combination of the yarn counts of the plurality of warps and the plurality of wefts, a total number of threads and a material composition ratio of the warps and wefts required for the vibrating diaphragm are achieved.

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.

A three-dimensionally printed article comprises a build material and a support material, the support material comprising a hydroxypropyl methylcellulose having a DS of at least 1.0 and an MS of at least 0.6, wherein DS is the degree of substitution of methoxyl groups and MS is the molar substitution of hydroxypropoxyl groups. The support material can be removed from the build material by contacting the support material with water.

Provided herein are devices and systems for depositing a material or manufacturing a product, such as a pharmaceutical dosage form, by additive manufacturing. Further provided are methods of using the devices and systems, as well as methods of manufacturing a product, such as a pharmaceutical dosage form, by additive manufacturing. In certain embodiments, the device includes a material supply system configured to melt an pressurized a material, a pressure sensor configured to detect a pressure of the material within the device, and a control switch comprising a sealing needle operable in an open position and closed position. The sealing needle extends through a feed channel containing the material and includes a taper end, wherein the tapered end of the sealing needle engages a tapered inner surface of a nozzle to inhibit flow of the material through the nozzle when the sealing needle is in the closed position.
