Abstract
A method of making and using a stretchable film includes an extruding operation where molten plastics materials are extruded into a tube and a blowing operation in which the tube is blown to expand a diameter of the tube and form a blown-film tube. The blown-film tube is slit to form a film sheet that may be deformed elastically in a machine direction.
