The aim of the invention is to produce envelopes (1), which avoid the use of self-adhesive adhesives that are supplied using conduits or similar. This is achieved by an envelope (1) comprising a blank with two lateral flaps (23), a base flap (8) and a sealing flap, with or without a window (6). The blank consists of paper or a paper substitute, the interior of said blank being partially or entirely coated with thermoplastic plastic, to which the lateral flaps and base flap are fixed. |
