PAPER WITH IMPROVED STIFFNESS AND BULK AND METHOD FOR MAKING SAME
摘要:
The invention provides a three layer reprographic paper having i mproved strength, stiffness and curl resistance properties and a method for making same. The paper has a central core layer (12) made largely of cellulose and bulked with a bulking with a bulking agent such as a diamide salt.A starch-based metered size press coating is pressed on both sides of the core layer wherein the starch has a high solid content. The coating (14) forms a three layered paper having an I-beam arrangement with high strength outer layers (14) surrounding a low-density core.
