  48. 48. 《 The characteristics of folding carton3.1 The bearing characteristics As we all know but may not pay special attention to the phenomenon: the bearing force of flat sheet cardboard is small, once creasing and properly folded, it could bear great pressure. 48 / 93 http://www.packmage.com
  49. 49. 《 The characteristics of folding carton3.2 The influence of the two sides of the paper on structure design No matter ordinary cardboard or corrugated board has two sides, ordinary cardboard has a surface layer and a bottom layer, corrugated cardboard has out layer paper and inner layer paper. It influences the molding when folding, which need to be taken into account in the structure design. ( a ) Inner fold 90° ( b ) Outer fold 90° ( c ) Inner fold ( d ) Outer fold 1-bottom layer 2-surface layer 3-bottom layer 4-surface layer 49 / 93 http://www.packmage.com
  50. 50. 《 The characteristics of folding carton3.3 The influence of the two sides of the paper on structure design There is an example : Caliper 2mm, Length 40mm.The creasing line is on the middle of the cardboard. Then we start to fold. 50 / 93 http://www.packmage.com
  51. 51. 《 The characteristics of folding carton3.4 The influence of the two sides of the paper on structure design Therere two concerns: 1. the length of the cardboard is 40 mm before folding, after folding the inner size isnt 40/2=20mm,it is 19mm because of the caliper. 2. The first statement is not entirely accurate,because of the two sides of the paper, when folding on the middle, the internal loss is different with different specifications of the cardboards, it need to be taken into account. 51 / 93 http://www.packmage.com
  52. 52. 《 The characteristics of folding carton3.6 The Offset Because of the dust flap under the cover, to be strictly the panel connect with the cover should add a caliper, else the cover will be hindered by the dust flap when folding. The additional caliper is offset. 52 / 93 http://www.packmage.com
  53. 53. 《 The characteristics of folding carton3.7 The texture direction During the folding carton manufacturing process, the creasing line can effectively control the cardboard deformation, its role can not be ignored.As the fiber orientation, so that the cardboard folding onthe creasing line, the force on the transverse indentation line (the line parallel to the creasing line) is bigger than the longitudinal creasing line (the line parallel to longitudinal creasing line), so the bounce of transverse creasing line is bigger, thus increasing tension of the cardboard surface and enhance the strength of the carton. As the fiber alignment, and the stiffness and binding force for the same kind of cardboard longitudinal fiber were greater than the transverse, which leads to the longitudinal stiffness greater than the transverse board; in addition, because most of the carton stacking flat folded for transportation and storage, so the carton need resistance to repeated folding to avoid the creasing line crack which might affect the appearance and strength of carton. Thus when design the texture direction of the folding cartion, it needs to consider the different of vertically and horizontally physical properties of the cardboard and the creasing line position. 53 / 93 http://www.packmage.com
  54. 54. 《 The characteristics of folding carton3.8 The texture direction design of TubesGenerally, the longitudinal texture shouldbe vertical with the main creasing line(longer creasing line).Advantages :• It makes the 4 surfaces of the box body smooth, avoid ballooning phenomenon.• It is helpful to high speed gluer machine.• The creasing line is not easy to burst and break(especially on thick paper ).When the carton size is smaller andaccuracy requirement is not too high, itcould apply mixed step and repeat ignorethe texuture direction, thereby saving cost. 54 / 93 http://www.packmage.com
  55. 55. 《 The characteristics of folding carton3.9 The texture direction design of Tubes with curved surface The bending resistance of the sheet transverse(parallel to the texture direction) is smaller than longitudinal,which means the cardboard transverse bending easier, with the curved surface, the texture direction of the folding carton should be perpendicular to the curved creasing line. We can clearly the horizontal of box a is easy to bend so that the box body is formed into a very smooth arch.While box b on the contrary, because the creasing line design of paperboard is unreasonable caused the box body distortion. 55 / 93 http://www.packmage.com
  56. 56. 《 The characteristics of folding carton3.10 The texture direction design of Trays The length direction of the tray folding carton should be perpendicular to the longitudinal direction of the cardboard.In this case it provides higher stiffness in a short span, facilitates the cartons strong and straight, and the transverse creasing line on the length direction gives the carton more strength. 56 / 93 http://www.packmage.com
  57. 57. 《 The characteristics of folding carton3.11 The texture direction design of regular polygon trays The texture direction design of the regular polygon tray, one plan is the longitudinal cardboard parallel to one of the box bottom corner angle bisector, another is longitudinal cardboard vertical to one of the box bottom corner angle bisector.Both two kinds of texture design have deficiencies, both affected the carton folding. The hexagonal box also has the problem. With the increase of the number of polygon box bottom, gradually tend to circle,the circle has no direction, so the more sides the polygon tray has, the smaller difference of the two kinds of plans, but the best choice is texture direction design which the board longitudinal vertical to the bisector lines of the bottom angle. 57 / 93 http://www.packmage.com
  58. 58. 《 The characteristics of folding carton3.12 The texture direction design For irregular folding cartons, the texture direction design should obey the basic cardboard texture direction design rules, but the irregular box has uncertainty, we suggest make samples to test first then choose which one texture direction design is more reasonable. 58 / 93 http://www.packmage.com
  59. 59. 4. Mathematics in the folding carton structure design Mainly because of the mechanical and physical properties, the folding carton structure exist many mathematical relationships. 59 / 93 http://www.packmage.com
  60. 60. 《 Mathematics in the folding carton structure design4.1 How to decide the inner size of the carton box We often see some carton For example, if the product size is 10*10*15 packaging rupture, deformation cm, caliper is 1mm, the inner size of the carton during transportation,this kind of box should be 10.1*10.1*15.2cm. circumstance except the paper strength is not enough, collision, one big issue is packaging size relatively big than the product. Generally, the length and width of the inner size of the carton box should be one caliper larger than the product, the depth should be 2 times caliper larger than the product. 60 / 93 http://www.packmage.com

  62. 62. 《 Mathematics in the folding carton structure design4.3 Tube folding carton structure design 1. The straight line on the inserted cover for friction locking function, the size of the cover changed based on the carton size, generally it is 20mm, with two R angles; 2. Glue flaps 10-16mm ; 3. Compare to outter layer the inner layer sealing face should be smaller; 4. The angle of the dust flap should be less or equal than 15 °; 5. The dust flap size should be smaller than the width of the box; 6. The outter layer sealing face size less or equal to the width of the box; 7. The right side face size is slightly less than the width of the box 0.8mm; even for heavy cartons, should reduce the cardboard caliper because the glue flap and right side face are jointed together, there will be one more caliper on the right side face. 62 / 93 http://www.packmage.com
