Abstract Ozone application to an extrudate web has been used for over a decade to enhance adhesion of polymer to the substrate in the extrusion coating process. However, to date, ozone’s effectiveness has not been quantified by published statistical data. A two-level fractional factorial design consisting of 64 experimental runs was utilized to study the…
Read MoreSurface Treating For Solar Cell Converting
The art of optimizing continuous processing techniques for flexible materials has long been practiced in the converting industry. The accrued benefits range from consistent product quality and waste minimization to lower conversion cost per square meter. And a key component in the optimization of many web converting processes is consistent and uniform surface modification by…
Read MoreThe Effect of Time and Contact on Corona Treated Surfaces
The effect of time and surface contact on corona treated material can be measured and evaluated. Both components cause degradation of dyne level readings of wettability. However, the most significant cause, though it can be isolated, cannot be completely eliminated. A solution to the problem is possible but requires cooperation between material producers and converters.
