A postal packet for containing one or more objects with two-dimensional development, such as, for example, a ticket for entrance or invitation to shows, musical or sporting events, a credit card, a discount coupon, or an advertising leaflet or brochure, is constituted by a sheet of paper that is folded at the centre so as to define a front leaf that is folded like a book on a rear leaf so that it can be glued on the inner face of the latter along the four peripheral edges in order to provide a sort of frame, which is more or less large, around a non-glued area that constitutes a housing in which, before completing gluing, it is possible to introduce a two-dimensional object, such as a ticket or an advertising leaflet or the like, which is then accessible to the user thanks to a pre-set tear-open contour line that favours tear opening, on the front face of the packet, of the covering portion, using a purposely provided gripping tab available on one side. |
