Abstract: Sustainable paper-based packaging materials, e.g., paper-based food packaging materials, are described. The packaging materials are based on paper formed from fiber derived from waste biomass, such as hemp hurds, mixes containing hemp hurds and hemp bast fibers, bagasse, and cocoa pod husks. Also described are methods of making the packaging materials. The methods can include environmentally friendly pulping and/or bleaching processes.

Abstract: Disclosed are non-treated, creped tissue webs, and tissue products produced therefrom, having low stiffness and surface lint. The inventive products may be produced by a print creping process adapted to dispose a non-crosslinked latex polymer on at least one of the outer surfaces of the tissue product. The non-crosslinked latex polymer creping composition does not negatively affect stiffness such that the products generally have a Stiffness Index less than about 5.0, such as from about 2.5 to about 5.0.
