Thye concept was to create a multi-level thermoforming incorporating an opening tab and all round perforation to enable easy opening by the consumer.
We used matched metal tooling to create a perforation around the entire perimeter of the blister, which is heat-sealed to the paperboard insert. Custom tooling was used to create a pull tab marked with an arrow at the very top of the package so the consumer intuitively knows to pull this tab to access the package contents. When he does, the PET blister separates along the perf and the top comes off smoothly. Both the perforation and 3D trimming were achieved using Punch and Die.
