Carton compression tester using process and test method

Determine the carton safety anti-stress, weight quality indicator standards ,

Both of the above indicators can be obtained through formulas. The determination of indicators depends on the difference between internal and external sales and storage period . Under special circumstances , if the cartons are supported by contents , the appropriate pressure resistance values ​​can be determined according to the actual situation . Weight quality indicators must be determined by formulas .

Check the pretreatment status:

After the 24h pretreatment carton (typically cartons user fairness unconditionally test means can test the authority) under standard test re-test state, the moisture carton dynamic equilibrium state,

Sample extraction notes:

In the trial production phase of new products , the difference between non-printing and die-cutting strength after sampling sample printing and die-cutting process is about 5-20%, so the state of the sample and batch product should be kept basically the same .

Sampling quantities of products should be consistent with the principles of statistical probability, after years of practical experience, sampling the samples shall be taken from six in three different packages, can reduce the risk of miscarriage of justice,

The result is judged:

If the carton pressure resistance detected under standard conditions is lower than the anti-pressure index , it can be determined that the batch box is unqualified .

To improve the efficiency of stacking test: stacking code testing often takes a long time , and the economic and effective assessment methods are still in the stage of exploration . The following are the experiences we have discussed and practiced with our customers .

The basic principle of carton compression tester :

The pressure value of the same box is equal to the value of the stacking quality. The minimum value of the pressure resistance of the sample is not less than the value of the safety pressure. By checking the average value of the pressure peaks of the 6 boxes, the stacking test can be qualified. , we can intuitively understand their related relations through the figure below .

Carton compression tester process and method :

We tested the data to understand the carton experience anti-stress peak deviations, under standard atmospheric conditions:

Under the conditions of handling, transportation, warehousing, etc., the maximum Max of the pressure peak of the same corrugated cardboard box deviated by about 28 % from the minimum Min, and the deviation of the single-wall corrugated box was about 33 % . (The individual seriously damaged boxes should be removed. )

Determine the average value of standard safety pressure :

The average value of the standard safety pressure against double corrugated boxes is usually 1.15 for safety and pressure resistance ( higher than 15 % for safety pressure resistance ), and the average safety and pressure resistance for a single corrugated box is 1.18.

Anti-stress peak detector 6 samples in the standard state cartons, carton seeking anti-stress peak sample arithmetic average, the arithmetic mean of the sample cartons anti-stress peak is greater than the average pressure resistant safety standards, the batch of cartons passing, and vice versa it failed,

The above method has strong operability , and it is of great benefit for improving work efficiency and evaluating stacking test results more effectively . You may wish to try
