Abstract: A method to accomplish manufacturing of cartons, that supports the objective to decrease relatively large volumes of unnecessary air shipped, and to standardise size aspects of raw material so that logistics of raw material use for cartons and carton manufacturing process can be optimized. The method comprise steps from the retrieval of measurements for intended content to be closed, to calculating required width and length of standardized sized carton pieces having width dimensions based on geometrical series 2, 4, 8, 16, 32, 64, and then cutting and re-join cardboard pieces edge to edge by an adhesive, to assemble a carton piece that matches a calculated required cardboard size for further forming and folding of a cardboard box, as described by the method, with minimal loss of carton material.
