New thermoforming simulation software enables developers of pharmaceutical packaging to project final formed thickness and barrier performance of blister packaging. Thinning of the blister film during forming can be significant and highly inconsistent within a single cavity as well as from cavity to cavity, leading to inconsistent barrier properties, the supplier says. This software helps eliminate guesswork in material selection and tool design. The developer, Amcor Flexibles Healthcare Inc., Mundelein, Ill., recently licensed Montesino Associates LLC, Wilmington, Del., to use the software as a service bureau providing custom simulations.
The finite-element simulation, called Black Box, is claimed to be the industry’s first product that provides pharmaceutical packaging companies quantifiable projections of finished blister thickness at multiple points within each cavity, as well as corresponding barrier performance for each cavity. It has been used mainly to simulate blisters of PVC, PVC/PVDC, and PVC/PCTFE, but it has also been used for COC and some other materials.
