What can be done to avoid over-/undertreating substrate surfaces?
Establish a continuous quality product by assuring assure that the resins are added in proper proportions prior to extrusion. Purchase quality resins and train your plant personnel to note the need for a change in the power levels of the corona treater power supply. Begin your process by establish a beginning point for the power level and work your way up on power till the anticipated dyne level is achieved; this being done through QA dyne checks of the film. Once the power level is established for the given product at the given speed, note the power level, re-use it next time, and you are assured of desired dyne repeatability.
