Material Characterization of Heat Shrinkable Film

摘要

Shape memory polymers represent a class of polymers that display properties of shape change under stimulus. The presented research focused on material characterization of thermally stimulated shape memory polymers, more specifically heat shrinkable bands often used as packaging in the food and the medical industry. Increasingly, regulatory agencies are pushing for the use of non-PVC materials industry wide. This study represented an experimental approach for evaluation of polyester shrink bands (non-PVC) in comparison with PVC with regard to thermomechanical and shrinkage properties.
