How do you check ply in corrugated box?
The strength of the corrugated box can be divided into categories – 3, 5, 7 and 9 plies. Depending upon the kind of products used and the way of handling needed the ply value of the boxes can vary. For instance, a 3 ply corrugated box will have one fluted paper placed between two-line boards.
How do you calculate the safety factor for a corrugated box?
The stacking safety factor is determined according to the number of stacking layers of the goods. According to national standards, for storage periods less than 30d, k = 1.6; for storage periods of 30d-100d, k = 1.65; for storage periods greater than 100D, K = 2.0.
