Adhesives used in bookbinding create a strong, lasting bond between various materials, such as paper, cloth, leather, and board. Different adhesive types are suited to specific binding methods and materials. For instance, perfect binding, common in paperback books, often employs a hot-melt adhesive, while more traditional case binding might utilize polyvinyl acetate (PVA) or animal-based glues.
The selection of an appropriate adhesive is crucial for the book’s longevity and structural integrity. A strong bond ensures pages remain secure, preventing them from falling out and contributing to the book’s overall durability. Historically, animal-based glues played a vital role, but modern advancements offer synthetic options with improved performance and handling characteristics. This evolution reflects the ongoing pursuit of more efficient and archival-quality binding methods.
