Abstract: A protective wrap material enclosing a stack of cut sheets of paper is folded so that overlapping flaps of the wrap material cover opposite ends of the stack. The overlapping flaps are secured and sealed together only at selected areas that comprise a minor portion of the overlapped flaps, wherein the sealed areas have sufficient burst strength to avoid inadvertent opening of the wrap but at the same time are relatively easy to separate when it is desired to open the wrap to gain access to the cut sheets of paper. In a preferred embodiment the wrap material is heat sealable, and a modified heat plate for applying heat only to the selected areas has a grooved front surface defining heat focusing bars that concentrate heat sufficient to fuse the wrap material only in the selected areas.
