SIMULATION OF THE PUNCTURE RESISTANCE OF A THERMOFORMED SYRINGE PACK

摘要

A potential material change for a medical packaging thermoformed pack requires costly and time-consuming re-validation. One of the major issues associated with this is the puncture resistance of the pack. This study considers a non-isothermal computational fluid dynamics (CFD) analysis of the thermoforming process of a syringe pack, followed by a non-linear structural analysis of the formed pack to estimate puncture resistance. In this way the final shape and thickness distribution of the thermoformed pack are included in the structural analysis. Two reference materials will be used in validating the usefulness of the technique.
