Abstract: The invention provides novel thermoplastic films produced by the blown tube process having improved and balanced characteristics. The improved film is characterized by crystallites dispersed throughout the film in amorphous areas and which is substantially free of crystalline formation, as well as having improved other properties. The film is produced by acting on a molten tube following extrusion to cool the tube to a temperature above the crystalline formation temperature, followed by an annealing step and a second cooling step to initiate solidification of said tube.
