Develop modular structures for each size and weight of the products. It would work in a way that for a heavier product, for example, the structures used for lighter products are assembled to each other/or in each other, to deliver a greater structural resistance. The sum/attachment of the smaller packaging products could build the appropriate structure to hold the heavier packaging product. This way, the less weight the less structure needed, the more weight the more structure needed. From simple to complex, maintaining the functions needed.
