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.

Claims

1. A shaped body consisting essentially of an alpha-glucan having a molecular weight of about 10,000 to about 10,000,000 comprising repeating units of [3)-Glc-(1→

4)-Glc-(1→

4)-Glc-(1→

], wherein Glc represents an alpha-D-glucopyranose residue.

2. A product in accordance with claim 1 wherein said shaped body is composed of said alpha-glucan alone.

3. A product in accordance with claim 1 wherein the shaped body is in the form of a tube.

4. A product in accordance with claim 1, wherein said shaped body is composed of said alpha-glucan in combination with a plasticizer or filler.
