Gift wrapping material is formed in a monolithic, one-piece body of undefined, length. The body is divided into a plurality of bag-forming sections by tear lines, and each tear line is spaced from an adjacent tear line so that tear-off strips are formed when two adjacent tear lines are torn. A tear-off strip is used to tie a bag closed. The bag-forming sections are formed of multiply plastics type material, and some sections of each bag are formed so that application of hot air thereto will cause those sections to shrink to a greater degree than adjacent sections to permit a bag to snugly enclose a multi-cornered package.
