Corrugated Industry Reject Rate

A question was asked at a recent AICC Education session as to whether there existed a corrugated industry average for typical return or rejection rate expressed in PPM(parts per million).

We reached out to some of our members for input on this question. If anyone else would like to share their knowledge or opinions, just leave a comment on this post. We’re interested in what you have to say!

From Joe —
There is no specific industry average that I’m aware of. We have tracked DPPMs (Defective Parts Per Million) monthly at all of our manufacturing facilities for years. Our goal is to be less than 1,500 DPPMs per month. That valve was an arbitrary standard set by Eastman Kodak Quality Engineers 10+ years ago. It translates into a defect rate of .15% or 99.85% good product. The goal is obviously 100% but you need some bar/standard to work against. In March 2012, we reset the bar to be less than 1,000 DPPMs per month. Our current defect rate of .0300% and we’re continuously working reduce it even farther.

From Ralph —
It was the consensus among the intergraded companies at the 2012 Summer Corbotech meeting that a reject and return rate of 3500 pieces per one million would be a very good rate. They felt that a rate of 0.5 to 1% on large runs would be typical. These are not numbers we publish as an industry. Not exactly six sigma!

Again… If you would like to share their knowledge or opinions, please feel free to leave a comment.
