Abstract: The present invention relates to a polymer composition comprised of gellan, carrageenan and mannan gums and a process for producing flexible films for encapsulation comprising the gellan, carrageenan and mannan gum composition. The mannan gums include the galactomannans and the glucomannans. Advantageously, soft capsules of the above composition are produced using the novel process. The composition comprises a blend of a gellan gum: (carrageenan/mannan gum) wherein the gellan gum concentration ranges from about 0.1 to 50 weight percent and the ratio of carrageenan/locust bean gum ranges from 3:1 to 1:3. Additional reagents are added to this gum blend to form a film-forming polymer composition useful in the production of gelatin-free capsules or microcapsules.
