A method for producing a portion unit with at least one filled receiving chamber surrounded by a film, comprising the steps of a) transporting a first film in the direction of a heating device; b) bringing the first film into contact with a surface of the heating device; c) heating the first film by means of the heating device; d) breaking the contact between the first film and the heating device; e) molding the first heated film into the cavities of a thermoforming mold, thereby forming a receiving container with at least one receiving chamber; f) filling the at least one receiving chamber; g) optionally closing and separating the filled receiving containers, thereby forming the portion unit, wherein the region on the surface of the heating device that is brought into contact with the film has at least one depression and, in step b), the at least one depression is covered by the subregions of the first film that are molded into the cavity of the thermoforming mold in step e).

Provided are compositions and methods for the instant hydration of polyacrylamide granules of particle size greater than 500 m comprising the same polyacrylamide powder of particle size less than 500 m; and a binding agent or agents. More particularly, the polyacrylamide powder is combined with a water-destroyable binding agent forming polyacrylamide granules, which instantly hydrates when added to water.

Described herein are water-soluble, non-toxic, thermoplastic polyurethane compositions comprising reaction products of one or more aliphatic diisocyanate compounds, one or more higher molecular weight polyalkylene oxide compounds having a molecular weight of 600-150,000 g/mol and one or more low molecular weight diol chain extender compounds having a molecular weight of 50-300 g/mol, reacted in molar ratios of 50:49-20:1-30 and having a soft segment content of at least 80% and methods for their synthesis and use.

A water-soluble film comprising a mixture of a polyvinyl alcohol (PVOH) resin, a plasticizer, and a metal salt, wherein the metal salt is present in the water-soluble film in an amount sufficient to reduce the enthalpy of melting of the film by at least 20% compared to the enthalpy of melting of an otherwise identical film not comprising the metal salt.

Glycerin and sodium polyacrylate may be mixed at a first mixing speed for a first mixing time. Free water and a fibrillated cellulose mixture may be added to second mixer and mixed at a second mixing time speed for a second mixing time. The glycerin and the sodium polyacrylate may be mixed with the free water and fibrillated cellulose mixture at a third mixing speed for a third mixing time. One or more of sodium citrate, sodium bicarbonate, and sodium benzoate may be added and mixed at a fourth mixing speed for a fourth mixing time. Sodium carbonate may be added and mixed at a fifth mixing speed for a fifth mixing time. A surfactant mixture and optionally fragrances may be added and mixed at a sixth mixing speed for a sixth mixing time to form a final mixture, which may be transferred to molds, dehydrated, and removed.

Build materials and methods of 3D printing are described herein. In one aspect, a build material comprises an acrylate component, a photoinitiator component, and a porogen component, wherein the porogen component is water soluble. In some embodiments, the porogen component is present in the build material in an amount of 55-75 wt. %, based on the total weight of the build material.
