Effect of heat treatment on tensile properties and inner structures of polyethylene thin films: comparative study on different polyethylene structure

摘要

Polyethylene (PE) is one of the mostly used plastics. With the different synthesized process, PE can be produced in various kinds of structure. High-density PE (HDPE), low-density PE (LDPE), and linear low-density PE (L-LDPE) are different structure of PE which can be applied in wide applications. In this study, three kinds of PE thin films are treated by heat for different time. Tensile properties and inner structure of heat-treated PE are evaluated and compared in order to investigate the different of degradation behavior from heat treatment. This study expected to be the guideline for regeneration properties of PE.
