We have a lower specification of 1.0lbf/in for pouch peel strength, and our sample size is 4 pouches per lot. Our process is not always stable and has inherent large variation, meaning that we do get values that range from around 1.0lbf/in to 10+ lbf/in. The Cpk that I calculated from the peel strength values is only 0.8.
Can someone give me advises on how to segregate the Pouch Sealing process variation from the overall of Pouch Seal + Peel strength testing? The strength of the seal cannot be measured without peeling it, and they are 2 separate processes with variations of its own coming from the equipment used, operators, methods, etc. How do I isolate the process variations from these 2 processes so that we can reduce the variation?
Thank you
