Answer to Question 1

The advantages of a cast film are clarity, thickness control, and the ability to use higher molecular weight resins and thus achieve improved physical properties. A disadvantage of cast films is that they cannot be produced as quickly as can blown films.

Answer to Question 2

Because of the ability to use flexible molds in casting, deep undercuts, high surface details and other design features that would be difficult to mold with other processes can be done easily by casting.
