ABSTRACT:
Biaxially oriented film is post-treated by an annealing process in a limited temperature range of 45.degree. C. to 120.degree. C. for various time periods based on the temperature for annealing in order to produce a film having less than a 0.2% shrinkage in the machine direction as measured at 51.7.degree. C. for 24 hours. This film has a wide range of uses, such as overwrapping film.
