A method for producing starch soft capsules comprises the following steps: preparing a mixture comprising starch, plasticizer and water, wherein more than 50 weight percent of the starch is present in the form of particles of granular starch; shaping the mixture to form a film in a shaping process; solidifying the mixture by increasing the temperature of the mixture during and/or after the shaping process by more than 5&#xb0; C.; and shaping the film to form a soft capsule. Soft capsules produced by this method have starch particles bonded to one another. A device for performing this method comprises a shaping device to enable shaping of the starch material to form a film, and a heating device to perform a heat treatment to destructure the starch during and/or after the shaping. It comprises a rotary die device.

A starch-based coating compound for packaging materials, in particular for paper, pasteboard or cardboard, wherein the starch has a molecular weight in the range of 800,000 to 50,000,000 g/mol, preferably in the range of 800,000 to 20,000,000 g/mol. The coating compound is used for surface-sealing packaging materials, to prevent the passage of mineral oil contaminants from the packaging material into packaged goods. The subject disclosure furthermore relates to a multi-layer packaging material, which is produced using the coating compound, and to a method for producing said packaging material.

The present invention relates to a polymer mixture with a low viscosity, allowing processes for the processing of plastics materials to be accelerated while the final properties of the end products remain the same or are improved. The polymer mixture is mixed with the plastics materials in the manner of an additive. The invention further relates to the production of suitable polymer mixtures of this type and to the use thereof.

The invention relates to a novel Mogul procedure for manufacturing sweets, in particular starch-based gummi candies, which have a comparable texture to gelatin-based gummi candies, with at least one portion of the starch not being completely dissolved until after the pouring into the form of the confection article. In comparison to previous Mogul technology, the casting mass is poured at a comparatively low temperature, and the gelling and/or settling occurs at a comparatively high temperature.

A method is disclosed for producing elastomer compounds for use in the production of rubbers. At least one elastomer to be processed for the production of an elastomer mixture can be slowly added to a mixer/extruder and is mixed and plasticized and/or masticated (melted) while it passes through the mixer/extruder. The elastomer, when slowly added to the mixer/extruder, can be present in a fluid medium in an evenly distributed form.
