Prohibitive Materials may not exceed 1/2 of 1% Outthrows plus prohibitives may not exceed 1% Other papers may not exceed 10% Specialty Grades The grades listed below are produced and traded in carload and truckload quantities throughout the United States, and because of certain characteristics (i.e., the presence of wet strength, polycoatings, plastic, foil, carbon paper, hot melt glue), are not included in the regular grades of paper stock. However, it is recognized that many mills have special equip- ment and are able to utilize large quantities of these grades. Since many paper mills around the world do use these spe- cialty grades, they are being listed with appropriate grade numbers for easy reference. The Paper Stock Industries Chapter of ISRI is not establish- ing specific specifications, which would refer to such factors as the type of wet strength agent used, the percentage of wax, the amount of polycoating, whether it is on top of or under the printing, etc. The specification for each grade should be determined between Buyer and Seller, and it is recommended that purchase be made based on sample. These specialty grades are as follows: 1—S White Waxed Cup Cuttings 2—S PrintedWaxed Cup Cuttings 3—S Poly Coated Cup Stock 4—S Polycoated Bleached Kraft—Unprinted 5—S Polycoated Bleached Kraft—Printed 6—S Polycoated Milk Carton Stock 7—S Polycoated Diaper Stock 8—S Polycoated Boxboard Cuttings 9—S (This Grade No Longer in Use) 10—S Printed and/or Unprinted Bleached Sulphate Containing Foil 11—S Waxed Corrugated Cuttings 12—S Wet Strength Corrugated Cuttings 13—S (This Number Not Currently in Use) 14—S Beer Carton Scrap 15—S Contaminated Bag Scrap 16—S Insoluble Glued Free Sheet Paper and/or Board (IGS) 17—S WhiteWet Strength Scrap 18—S BrownWet Strength Scrap 19—S Printed and/or ColoredWet Strength Scrap 20—S File Stock 21—S (This Number Not Currently in Use) 22—S Ruled White 23—S Flyleaf Shavings Containing Hot Melt Glue 24—S (This Number Not Currently in Use) 25—S Books with Covers 26—S (This Number Not Currently in Use) 27—S (This Number Not Currently in Use) 28—S (This Number Not Currently in Use) 29—S (This Number Not Currently in Use) 30—S Plastic Windowed Envelopes 31—S Textile Boxes 32—S Printed TMP 33—S Unprinted TMP 34—S Manila Tabulating Cards 35—S Sorted Colored Ledger 36—S Computer Printout (CPO) 37—S Silicone Release Liner
