  • Patent number: 7887838
    Abstract: A film-forming composition comprising a hydrocolloid, a plasticizer, and water is described. A process and apparatus for producing a non-gelatin film comprising a hydrocolloid, a plasticizer, and water is also disclosed. The process includes combining at least one non-gelatin hydrocolloid, water, and at least one plasticizer into a substantially homogeneous film-forming composition comprising at least about 40 percent water by weight. A substantial portion of the water is then extracted from the film-forming composition to form a dried portion having a water content of less than or equal to about 25 percent by weight. The dried portion of the film-forming composition is formed into a film. A film produced according to the process preferably has a tensile strength at rupture of at least about 0.4 N/mn2, and a percent elongation of at least about 50 percent at rupture at room temperature.
    Type: Grant

The dried portion of the film-forming composition is formed into a film. A film produced according to the process preferably has a tensile strength at rupture of at least about 5 N, and a percent elongation of at least about 50 percent at rupture at room temperature. An apparatus for performing the process is also described, as well oral dosage forms encapsulated or enrobed in the produced film.

  • Patent number: 5459983
    Abstract: A medicine tablet is described as a new article of manufacture. The tablet is enrobed in a gelatin coating formed by application of respective layers of elastic gelatin film to opposite sides of the tablet. The applied gelatin layers conform tightly to the tablet surface, bond securely to the tablet, and are sealed together in essentially edge-to-edge manner at a seal line which extends around the tablet at a desired place on the tablet. The gelatin layers can be colored differently from the tablet and differently from each other. A range of formulations are described for film which can be peelable from a tablet or other product core, and for films which bond to the core. A presently preferred formulation for producing tablets having a bonded tamper-evident coating comprises a water-based gelatin preparation having about 45% gelatin and about 9% plasticizer (glycerin and/or sorbitol) by weight. Method and apparatus for producing such new products are also described.
