Abstract
Abstract Products such as film, sheet, paper, fiber, coating material, binder, and molded materials e.g. capsules, cups et al are disclosed. The products are prepared by use of an alpha-glucan comprising repeating units of [3)-Glc-(1→4)-Glc-(1→4)-Glc-(1→], (wherein Glc represents alpha-D-glucopyranose residue) as its sole constituent or a member of its constituents according to conventional methods.
