摘要

The method of making cardboard package for fruit and vegetables with increased resistance to moisture penetration is characterized by cutting form a cardboard a cardboard blank, whereupon the corresponding sections are bent and formed into the form of a cardboard open box. In the method, there is used a cardboard consisting of seven paper layers in combination with corrugated EBE, where three layers are corrugated, wherein the external waves (E) have the height 1.5 mm and the height of the cardboard is selected within the range of 5 to 6 mm. As a seven-layer cardboard in combination with the corrugated EBE , there is used a cardboard made of a low paper stock weight, whereby all over the production process, starting by the storage of raw material, as well as in the workshop, a minimum air temperature of 17 degC and a stable level of humidity about 50 percent are maintained.
