This delustered dull finish can be written on with ballpoint pen or pencil. 5 mils thick per flap is a popular thickness laminating pouch used in 98% of pouch laminators worldwide and provide protection with medium rigidity and cost. Also, most pouch laminators without a temperature adjustment will do no more than 5 mil laminating folders. These laminating pouches have small radius rounded corners for a professional finish. To leave a clear border of laminate around your sheet, we recommend no larger than 11-3/4 x 17-3/4 size paper to allow for the sealed edge and rounded corners. This size works nicely for menus, charts, signs, counter mats, placemats and more.
