Cardboard stacking shapes are nothing more than four: single-row parallel stacking; double-row parallel stacking; well-shaped sub-stacking piling code; multi-row layered cross stacking code. The advantages and disadvantages are as follows:
1.Single-row parallel stacking Advantages: The board can be fully radiated up and down, and around four weeks; positive and negative ones can be used to make the cardboard smooth;
Disadvantages: Cardboard center heat can not be distributed in a timely manner, which soft peripheral hard; stacking middle and lower cardboard corrugated also because of its soft, after the pressure thickness thin; upper board easy bow waist deformation.
2. Double-row parallel stacking In addition to the advantages and disadvantages of single-row parallel stacking, the stacking code has the following advantages and disadvantages: it occupies less trays and saves storage space; heat between two cardboards is difficult to disperse, causing the cardboard to be hard and soft.
3. Well-shaped sub-stacking piling code advantages: good cardboard flatness, no warping, due to special stacking methods, there is a gap between the layers and the middle of the wells through the tray, the air circulation, heat distribution, Fast, good strength, less trays than the above two stacking codes, saving space.
Disadvantages: Occupies 2/5 of the area of the cardboard overlap, moisture distribution is not complete; adhesive quality is slightly poor, the composite layer of paper is easy to crack; the number of cardboard between each layer will not be the same pressure deformation.
4. Multi-line layered cross stacking code Advantages: Compared with the above three stacking codes, the tray utilization rate is the highest, the floor space is the smallest, the cardboard flatness is the best, and the adhesive is slightly inferior and does not open the glue.
Disadvantages: paperboard hot air is not easy to disperse, making it soft; corrugated highly difficult to recover, cardboard due to thinning; due strength is also reduced, in severe cases, the thickness of five-layer paperboard dropped to 4mm below, three layers down to 2.5mm ( All other factors that affect the board thickness are normal.
Based on the above analysis, and considering the quality of the carton, it is obvious that the well-separated stacking piling code is the best choice.
