Patent ID: 7612116

Claim:
A process for manufacturing a gelatinized film for soft capsules, the process comprising: a) dissolving a thickening agent under mixing and cold conditions, the thickening agent having an instant gelatinizing property upon contact with complexing agent solutions, in aqueous or hydroalcoholic medium buffered or not, to form a viscous mass; b) solubilizing additives under mixing and cold or hot conditions in the viscous mass; c) vacuum degassing the viscous mass to eliminate the air from the viscous mass; d) transferring the viscous mass to a film formation system; e) forming a film from the viscous mass on drum systems at a temperature of about 10-15° C. to form a viscous film; f) instantaneously gelatinizing the viscous film by spraying or dipping, or both, in a complexing agent solution, to form a gelatinized film; and g) drying the gelatinized film through an air stream having a temperature comprised between −10° C. to 70° C.
