<UnorderedLists id="ula01" listStyle="none"><ListItem>a shrinking ratio in one axis is not less than 30% at 80°C and not less than 50 % at 100 °C, and</ListItem><ListItem>a shrinking ratio in a perpendicular axis to the former axis shows the minimum value at a temperature range of 80 ± 25°C, and the process therefor.</ListItem></UnorderedLists>

This film shows an excellent shrinking properties for packaging.
