    Sammanfattning : As the plastic and packaging industry is looking to increase the longevity of plastic products as well as recycling used material, there is a need to understand how material properties respond and change during long periods of mechanical loading. Physical tensile experiments on thin plant-based High-Density Polyethylene (HDPE) are conducted with the intent of capturing relaxation behavior from a short-term (1-3 hours) and long-term (29-56 days) perspective.
