Mullens VS ECT

I see a lot of the manufacturers on the west coast switching to ect as opposed to mullens tested boxes. This was a problem about 10 years ago with a lot of the end users as the main complaint with ect boxes were the actual thickness of the corrugated. It seems that is the first thing they noticed and for that reason they were rejected often.

I have noticed that most manufacturers on the east coast and in the south primarily stock ect board. It looks like the corrugated industry is aimed to move towards ect as the initial source of corrugated testing…. but will the end users adapt?
