SOLUBLE FILM

摘要

A soluble film which dissolves in water without leaving undissolved lumps, has excellent meltability in the mouth, and is excellent in film properties including dryness resistance and nonblocking properties. Incorporating at least one member selected from the group consisting of ?-polyglutamic acid and salts thereof into a film formed from a water-soluble polymer can give a soluble film greatly improved in meltability in the mouth and water solubility and less apt to decrease in moisture resistance and dryness resistance. Incorporating a gellant and/or a plasticizer into the soluble film can give an edible film having better film properties. The soluble film is used as a covering/packaging material or support for foods, medicines, cosmetics, etc. or as an edible filmy preparation containing any of various functional ingredients. In such applications, the film can have excellent film properties.
