Tianjin Carton Factory: Calculate the maximum stacking load Ps that can be borne by the bottom of the carton, that is, Ps= (Nmax-1) •G, where Nmax is the maximum stacking height and G is the weight of the contents and boxes。According to the requirements of SN/T0262-93 export transportation packaging corrugated box inspection procedure, select the appropriate safety factor K, when the storage period is less than 30 days, K=1.6;The storage period is 30 to 100 days, K=1.65;When the storage period is greater than 101 days, K=2.
Carton quality standards
Samples with puncture strength should be tested for four different Angle values: frontal longitudinal, anti-longitudinal, frontal transverse, and anti-lateral, respectively, and some companies are testing。It does not take into account the Angle of the test sample。In fact, in the actual detection, the test results of the four different angles of front longitudinal, rear longitudinal, front horizontal and rear horizontal are sometimes very different。
When the burst strength test is performed, the data of the secondary explosion sound should be discarded, or if the sample has significant slip, it should be determined separately。Both sides of the sample。In general, abnormal test data during test execution should be increased the number of tests to verify that the test results are accidental and to avoid making wrong decisions。
When the compressive strength of the carton was detected, the test was carried out without sealing, which would result in insufficient test data。The correct method should first combine the sample box in three dimensions, seal it up and down with a sealing tape, and then place it in the middle of the compression testing machine under the pressure plate, pressurizing at a standard speed until the carton is pulled out。
