Abstract
Method of lateral stretching of isotactic polypropylene films to obtain their molecular orientation, characterized in that the stretching is applied when the film is heated to a temperature comprised between the melting point of the polymer and 30º c. Below the mentioned melting point. (Machine-translation by Google Translate, not legally binding)
