Mr. Paul, If was involved in that project and after conducting the exact steps I will think about the pouch material "made of" every device manufacturer they design/build their devices base on specific ingredients of the material of these pouches. Let's assume that I would order few samples from different suppliers or I'll contact the manufacturer about more details. Can you please provide the confidence level of this regression! Thank you in advance sir.

If you're trying to compare suppliers the tool you need is ANOVA I would suggest. Most important you only have one supplier though, multiple suppliers of the same item is a recipe for disaster...

@@paulallen5321 Thank you for the warning, I have thought about it and understood your point of view. Good advice. I just bought your second book DOE, now I am happy that I've got both in my library. I'll be focusing on your books for the next steps. Your time greatly appreciated.

Hi Paul, why taking the lowest value can save money? For Y bar, the highest seal strength is 77.125 (Set 6), isn't that the best solution?

[@paulallen5321]

Hi Tan - row 6 looks best, but statistically it is producing no strong signal and the setting didn't confirm but it's not a bad idea to pick the best run and try it...
