<p>A method for producing a processed polymeric sheet to be adhesively secured to a cover to form a seal, the sheet having properties such that the seal does not have branching peel defects when it is separated. A polymeric sheet is formed from a source of polymeric material, and at least one side of the polymeric sheet is coated with silicone. The polymeric sheet is further processed while implementing a static neutralization method to substantially eliminate electrostatic discharge across the polymeric sheet during such further fabrication, producing a processed polymeric sheet. Preferably the polymeric material is selected from the group consisting of polyethylene, polystyrene, polyester, polyvinyl chloride, polypropylene, acrylics, acrylonitrile, polycarbonates, polyimide, and cellulosics. The static neutralization method, in different preferred embodiments, may be impregnating the polymeric source with a conductive material to dissipate a static charge on the polymeric sheet, coating the polymeric sheet with a hygroscopic material to attract moisture and dissipate a static charge on the polymeric sheet, at least partially ionizing an air mass and passing the polymeric sheet through the air mass to neutralize a static charge on the polymeric sheet, or passing the polymeric sheet near static neutralization bars to neutralize a static charge on the polymeric sheet.</p> |
