Some bending properties of films

摘要

AbstractMeasurements of the bending hysteresis of polyethylene, polypropylene, and poly(vinyl chloride) films are described. A Shirley Cyclic Bending Tester was used, and value for coercive couple, flexural rigidity, and bending recovery are given for low and medium curvatures, 0.4 and 4.5 mm−1, respectively. Bending in different directions and data for monofilaments and a tape are included for compariso
