Material reduction and greater sustainability were the key drivers behind this project: by bringing together the latest technology in both the light-weighting of the PE (Polyethylene) closure, plus the market introduction to the thinnest multi-layered PET (Polyethylene terephthalate) container.
The perfect positioning and alignment of the hermetic induction seal was key to ensuring an even seal on the container and obtaining the maximum performance. Getting the marriage between the closure, container and hermetic seal was important to the success of this project.
The brief for BMi was to develop a low cost method of confirming that this ‘perfect fit’ had been achieved between all three parts, whilst establishing a solid benchmark for future quality checks.
To this end, BMi developed a procedure to encase all three parts in solid resin; giving the capability to cross-section the mould at several desired positions around the circumference. This in turn, allowed for a closer inspection to ensure the position of all three elements remained constantly in-line.
These resin moulds can be stored for future quality references, so if any of the parameters were to change in manufacture, a production standard base-line still existed. This simple approach to a highly technical issue was quickly utilised and has proved to be very successful.
