The proportion of gum arabic is preferably 70% to 90% by weight of all components. The water-soluble polymer is preferably a hydroxypropylmethylcellulose or carboxymethylcellulose or alginetes. The hydrocolloid is preferably a carrageenan or agar gum or galactomannan or a mixture thereof. The capsule may be is containing medicinal or pharmaceutical agents as fill material. The capsule has good mechanical strength and low brittleness. The presence of gum arabic in a solution raises the solubility of other film-forming polymers.
