Hardback book backing with hot melt adhesive

HB Fuller of the United States has developed a full-back adhesive with a hot melt adhesive for hardback book backings. Can be used in different case materials, papermaking raw materials, production volume, line speed and equipment. This adhesive is 100% solids, does not contain animal protein, does not become brittle over time, and can replace protein-based backing adhesives used in conventional equipment.
