PTP包装における多層ラミネートフィルムのプラグ成形

－FEM解析と実験による成形限界線図の作成－

抄録

In recent years, due to advances in medical treatment, a wide variety of pharmaceuticals have been developed, and manufacturers are required to have packaging technology suitable for each pharmaceutical. From the viewpoint of quality protection of contents, PTP (Press Through Package) using multi-layer laminate film is being developed, but if the design conditions are not appropriate, the film may crack during the manufacturing process. Therefore, in this study, we try to predict the risk of fracture by creating a film forming limit diagram from the simulation of plug molding of laminate film by the finite element method and from the measurement of the principal strain by experiments.
