Abstract
Printable packaging paper for flexible packaging. A flexible overall print coating makes a first surface suitable for conventional printing. The print coating comprises clay, binder comprising acrylic and optionally PVOH, and microsphere shells, some optionally deformed. A barrier coating comprising PVOH, optionally acrylic, can be on the second surface. A multiple layer packaging structure can comprise such coated substrate and second and third strength layers of paper, and a flexible polyolefin barrier layer, all on the barrier coating side of the substrate, joined to the barrier coating. The flexible print coating can include titanium dioxide. The invention includes methods of making printing paper by applying first and second overlying acrylic or PVOH barrier coatings, calendaring the coated substrate in line, applying a flexible neutral-color print coating onto the first surface, including clay, binder comprising acrylic polymer, and polymeric microsphere shells, and calendaring the substrate a second time.
