Tom explained that extensive testing took place at Detpak's rapid innovation centre, LaunchPad.
“Our testing included sourcing chips cooked in the same environment, loading them into trial cartons, and allowing them to sit in an insulated bag for twenty minutes to replicate the food being delivered," Tom said.
“The temperature was measured to see how products had performed in the area of heat retention, but our main consideration for these trial cartons was always promoting a crunchy chip.
“We would pour the chips from test cartons onto plates, so they would be presented the same way. Then a series of test subjects would taste-teste and rank the chips in order of crunchiness.
“We performed this crunch test on several occasions, refining designs as we went."
