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
CELTEC TST-01 tensile tester has this protrusion puncture test program and jigs available for this application. Below are steps of setting up test for protrusion puncture test.
Remove the two standard clamps from tester base and loadcell.
This ASTM D5748 test method determines the resistance of a stretch wrap film to the penetration of a probe at a standard low rate, a single test velocity. Performed at standard conditions, the test method imparts a biaxial stress that is representative of the type of stress encountered in many products end-use applications. The maximum force and penetration distance are determined.
