Existing testing devices can usually only perform horizontal tensile tests on PE film, but cannot test the compressive properties of PE film in a stretched state, nor can they test the torsional resistance of PE film and the tensile properties at different angles. The test scope is limited. In order to address the shortcomings of the existing technology, we propose a PE film pressure tensile testing device. Utility Model Content
