  • Patent number: H1857
    Abstract: 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.
