According to the invention, by changing size and marginal features of the blank, it is possible to produce different trays satisfying quite different requirements. According to the present invention, the performance of the cardboard or cartonboard used is optimized by using strengthening members where they are most needed and thus lightening the general structure of the container, which is thus fundamentally different from the conventional one due to the significant increase in performance. The strength-conferring material is allocated only where it is needed, so that the quantity of fiber is dramatically lower in comparison with conventional chassis. Such a reduction is rendered possible by the use of the compression members which confer the required strength. According to the prior art, the final container is produced from a blank or chassis, in the entirety of which the quantity of fiber and the board grade are adapted to the performances required for the intended application. On the contrary, according to the present invention, the manufacturing of chassis of different board grades is avoided and the chassis can be produced with the lightest weight, whereas the satisfaction of different requirements is allowed by selection of the proper size and material grade of the compression members. The gist of the present invention thus resides in the presence of the compression members, whose size can vary and provide the flexibility necessary for adapting to the different requirements with the lowest possible weight obtainable today on a corrugator. In particular, the lid compression member offers assured retention during transit using minimal fiber and, therefore, offers a sustainable, light weight replacement option to the conventional shrink wrap. Furthermore, the tray structure with two lid compression members allows for significant reduction in fiber required to retain self-supporting products, such as, typically, cartons, aseptic blocks, jars or tins.
