Kind Code:
A1
Abstract:
[Problem] To provide a film molding composition whereby film solubility and strength are obtained at the same time, and a film. [Solution] Provided are a film molding composition, etc., including at least a first hydroxypropyl methylcellulose (HPMC), the viscosity of a 2% by mass aqueous solution of which at 20°C is 2.5-4.5 mPa∙s, a second HPMC in which said viscosity is 6.0-50.0 mPa∙s, a third HPMC in which said viscosity is 4.5-15.0 mPa∙s, a gelling agent, and a solvent, the film molding composition being such that: the first HPMC is selected from the three members including an HPMC-IA that belongs to group I and an HPMC-IIA and an HPMC-IIB that belong to group II; the second HPMC is the same member as the first HPMC, but a substitution degree DS and/or MS of the second HPMC may be the same as or different from the substitution degree DS and/or MS of the first HPMC; and the third HPMC is a member of a different group than the first HPMC. [Selected drawing] None
