Raw materials. the liners and medium that make up the corrugated sheet are both forms of paperboard. paperboard is made primarily from cellulose fibers found in wood. the fibers are held together by lignin . fibers are separated from the wood in one of three ways: mechanical, chemical, & semi chemical..
