The object of this invention is a tray for containing products (2) with reduced longitudinal dimensions, known as "non-cuttables", for the tobacco industry; the tray comprises a plurality of accumulation chambers (3), each of which is delimited by a rear wall (4), a base wall (5) and two side walls (6) and is designed to contain a layer of a plurality of the products (2) stored according to an ordered orientation and covering the entire surface of the rear wall (4); more specifically, the accumulation chambers (3) define modules (7) whose respective rear walls (4) are parallel to each other and the distance (D) between two rear walls (4) of two adjacent modules (7) is substantially the same as the reduced longitudinal dimensions of the products (2) contained therein; each tray comprises a plurality of stackable modules (7) which can be closed in a pack in such a way as to define the thickness of the tray itself; connecting and disconnecting means (10) are provided between each module (7) and another so that the tray may be composed of a variable number of modules (7).
