A-reusable envelope made, notably, of a flexible material such as paper. A method for manufacturing the envelope as well as a machine for manufacturing the envelope.

The present invention relates to a tamper-evident envelope element (1) of sheet material comprising: a rear wall (2), a first and a second front flap engaged with the rear wall (2) opposite to each other. The first and second front flaps (3, 4) are configured for defining a closed condition in which they partially overlap each other, and an open condition in which they are distanced from each other. The envelope 1 comprises a safety device (12) having a first coupling portion (13) borne by the first front flap (3), a second coupling portion (14) borne by the second front flap (4). The first and the second coupling portion (13, 14) are configured to engage stably with each other during first closed condition of the first and second front flap (3, 4); at least one between the first and second coupling portions (13, 14) has at least one removable portion (15) configured for separating from at least one between the first and second front flap after a first opening condition thereof subsequent to said first closed condition for preventing a subsequent coupling of said first and second coupling portion (13, 14). The present invention also relates to a process for manufacturing said element.
