this disclosure features use of a paper or polymer film that includes a slip agent that can transfer to its surfaces . once the paper or film is pressed against a glass sheet , this will leave a thin surface roughness of slip agent that can prevent or reduce glass surface scratches from other surfaces or particles during shipping or finishing , thereby improving the yield of glass shipments between glass forming plants and customers . the thin discontinuous layer of slip agent remaining on the glass surface can be washed off easily in subsequent washing processes . the paper or film can have the slip agent imbibed within the paper or coated on it as a surface member .
