M-real says research finds lighter weight Kemiart kraftliners make strong corrugated boxes

ESPOO, Finland, Nov. 29, 2010 (Press Release) - Independent tests carried out recently on behalf of M-real Consumer Packaging have confirmed that lighter weight primary fiber-based kraftliners provide better corrugated box compression strength than heavier weight white lined chipboard (WLC) or liners containing recycled fibers. Both cost savings and sustainability benefits can be gained by using stronger and lighter weight kraftliners in corrugated packaging. The tests, undertaken by an external research institute, compared corrugated trays in which only the white top liner varied.
