Chongqing packaging factory carton compressive strength estimation process

To accurately calculate the cartons compressive strength, we must measure the carton perimeter, the thickness of cardboard and cardboard marginal pressure strength, combining the structure craft carton on calculating values are revised. Side pressure strength can be calculated according to the horizontal ring corrugated layers of paper and paperboard compression strength of pit type. For there is no instrument factory, know that as long as the paper ring crush strength and the ring crush index, also can calculate the cartons compressive strength. It must be pointed out that, paper ring crush value must be objective and true, and the paper ring crush strength must be at 23 ± 1 ℃, 52 ± 2%RH temperature and humidity environment test values.

The cartons compressive strength calculation procedure as shown in Figure 6 as shown in (omitted).

The calculation formula of the cartons compressive strength

A large number of test data verification, we found the following formula to calculate the results close to the true value, and the calculation is simple, easy to master. This recommendation to you:
B=5.874×E× T×C
B=5.874 * E * T * C
B表现纸箱抗压，单位N
B said carton compressive, unit N
5.874为系数
5.874 for the coefficient
E表现纸板边压强度，单位N/m
E said the cardboard marginal pressure strength, unit N/m
T表现纸板厚度，单位m
T said the board thickness, unit M
C表现纸箱周长，单位m
C said carton perimeter, unit M

Give an example.

A specification for a common groove type 360mm * 325mm * 195mm cartons, pit pit for C, the board thickness is 3.6mm, compressive strength is 4270N/m, try to calculate the FCL compression value.

Problem solving:

The carton perimeter is 1.37M, the board thickness is 3.6mm, compressive strength is 4270 N/m

According to the formula: Carton compressive strength of B = 5.874 × E × T × C
B＝5.874 ×4270 × 0.0036 ×1.37
B = 5.874 x 4270 x 0.0036 x 1.37
B＝1755N
B = 1755N
