Abstract:
Methods of stretching thermoplastic films in the machine direction include elongating the films in the machine direction without significantly reducing the films' machine-direction tear resistance. In one or more implementations, methods of stretching thermoplastic films include reducing the gauge of the films while substantially maintaining the films' machine-direction tear resistance. The methods can involve uniformly cold stretching the films by stretching the films to a draw of about one hundred and eighty percent, or less, of the films' original length.
