Envelope printing

Envelope printing
  • Model: EP-1


An envelopes a packaging product, usually made of flat material such as paper or cardboard, and designed to contain a flat object, which in a postal-service context is usually a letter, card or bills.

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.
