Abstract
A method for predicting the drop impact resistance of a stretch-blow molded polypropylene container which comprises the steps of measuring the initial size of the container, placing it in an oven, remeasuring its size after removing it from the oven, calculating the percentage difference in size of the container and determining its drop impact resistance, which is proportional to said difference.
