PROBLEM TO BE SOLVED: To provide a forming method for a polyester-based resin wherein deposit to a die is less even when a forming is performed by using a high temperature die, and therefore, a container being excellent in physical properties can be formed at a favorable productivity. SOLUTION: In the forming method for a polyester-based resin, a spherical polyester-based resin particle of which the average particulate diameter is 1-6 mm, of which the maximum particulate diameter is 1.2 times or lower of the average particulate diameter, and also, of which the minimum particulate diameter is 0.8 or more of the average particulate diameter, is used. |
