ASTM D2923
Standard Test Method for Rigidity of Polyolefin Film and Sheeting
The rigidity of a polyolefin web can affect its machinability, particularly on those packaging machines where a cut portion of a web is required to remain flat momentarily without being supported on all sides. Rigidity is not a simple property since it depends on two other properties of the sample: the thickness (gauge), and the stiffness which is an inherent property of the material of which the film or sheet is made. The combined effect of these two factors is the rigidity that influences performance on converting machines.
Paper Softness Tester ZRD-T1
ZRD-T1 Paper Softness Tester measures the softness, stiffness and rigidity of tissue paper, toilet paper, fabrics, polyolefin films and other materials.
We hope this helps and as always, we aim to ensure we can help and be proactive.
