Speciality 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 equipment and are able to utilize large quantities of these grades.
Since many paper mills around the world do use these specialty grades, they are being listed with appropriate grade
numbers for easy reference.
The Paper Stock Industries Chapter of ISRI is not establishing 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.
