Standard Test Method for Protrusion Puncture Resistance of Stretch Wrap Film

Importancia y uso:

4.1 Puncture resistance is very important in end-use performance of stretch wrap film used in consumer and industrial product applications. Puncture resistance is a measure of the energy-absorbing ability of a stretch wrap film in resisting a protrusion. The test method is designed to provide the user with a means of measuring the stretch wrap film's puncture resistance performance under essentially biaxial deformation conditions. A biaxial stress is representative of the type of stress encountered by stretch wrap products in many end-use applications.

4.2 Although this test method cannot be expected to duplicate all field experiences, since the rate of speed, weight, and configuration of such destructive forces vary widely, a generally reliable comparison of samples may be made from the data obtained.
