Abstract
Laminate and method for protecting books using same. The laminate comprises a stiff rectangular sheet adhered through a pressure sensitive adhesive to a thin flexible transparent rectangular sheet, which is of the same height as but wider than the stiff sheet. The two sheets are juxtaposed so that 3 edges of each mutually coincide. The flexible sheet has a flexible rectangular side portion or extension to which the stiff sheet is not adhered. The stiff sheet is preferably of the same dimension as the book to be covered. To protect a book, one applies successively two laminates of preferred size so that each sheet is adhered to the outside of one book cover; and each flexible extension is adhered to the spine and the adjacent portion of the opposite cover. The back cover is preferably covered first. The laminates are cut to size when necessary. The spine and portions of each cover of a protected book have a two-ply covering, and the remaining portions of the book covers have one-ply coverings. This laminate is particularly useful for protecting paperback books and periodicals.
