ABSTRACT:
A laminating envelope has first, second and third rectangular panels which are sequentially secured together along longitudinal edges. Each of the panels has a front and a rear surface and at least one of the panels is transparent. The first and second panels are disposed in facial relation and the aligned edges thereof are secured together for providing a pocket between the panels. A score line in the third panel extends between the third panel side edges. The second panel side edges have a length exceeding the first panel edge length by at least the width of the score line and the third panel side edges are substantially equal in length to the second panel side edges. Adhesive is disposed over the first panel rear surface so that folding of the third panel along the score line causes the third panel rear surface to be in facial relation therewith and secured to the first panel rear surface by the adhesive for thereby securing and sealing the pocket.
