All webs are imperfect, but with worsening magnitude of imperfections waste increases, productivity decreases, and profits suffer.
This set of recommendations does not reduce the camber, bagginess, or curl in your product but aims to improve handling the imperfect webs with reduced waste.
Webs have do not lay flat or roll out straight due to variations in length versus CD position.
There are many methods to qualify or quantify bagginess.
A web has length or width variations through the thickness of the product and does not lay flat without the help of gravity or tension.
Curl can be predominantly in the MD, CD, but can also be strongest at an angle or seek to curl in all directions.
