摘要: 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.
