Sealing method for equipment boxes (G) comprises fitting a plastic sheet (F) on top of the box, so that its edge (1) fits exactly on its rim (R). The sheet is then laser-welded in place. The edge is transparent to the laser beam. Independent claims are included for: (A) equipment boxes as described; and (B) a set of equipment boxes in which the color of the central section of the sheet indicates the contents of the box. Gegenstand der Erfindung ist ein Verfahren zum Verschließen eines Gerätegehäuses (G), bei dem eine Folie (F) auf einen umlaufenden Rand (R) des Gerätegehäuses (G) gelegt wird, um das Gerätegehäuse (G) zu verschließen, bei dem der den umlaufenden Rand (R) des Gerätegehäuses (G) bedeckende Teil (1) der Folie (F) mit Laserstrahlen bestrahlt wird, um die Folie (F) mit dem Gerätegehäuse (G) zu verschweißen, wobei der den umlaufenden Rand (R) des Gerätegehäuses (G) bedeckende Teil (1) der Folie (F) im Wesentlichen transparent für die Laserstrahlen ist.
