Envelope
An envelope is a
packaging product, usually made of flat, planar material such as
paper or cardboard, and designed to contain a flat object, which in a postal-service context is usually a
letter or card. The traditional type is made from a sheet of paper cut to one of three shapes: the
rhombus (also referred to as a lozenge or diamond), the short-arm cross, and the kite. These designs ensure that in the course of
envelope manufacture when the sides of the sheet are folded about a delineated central rectangular area, a rectangular-faced, usually oblong, enclosure is formed with an arrangement of four flaps on the reverse side, which, by virtue of the shapes of sheet traditionally used, is inevitably
symmetrical.
