Dust Jacket Sleeving. Unifold dust jacket sleeving is a highly durable and effective covering for hardcover books with dust jackets. Consisting of a plastic front and a paper backing, it forms a protective sleeve around the dust jacket and around the book ends, holding the cover securely in place. This style of book covering has been used for decades in libraries, bookshops and by private collectors.
Not only does Unifold protect your valuable books while enhancing their appearance, it also can be removed from the book without any evidence that it had ever been used, preserving the value of the book.
