A simple understanding of the carton compression testing machine and its correct use.

Good compressive performance can ensure that the contents are not damaged during transportation and storage; at the same time, it can also guide the production of packing boxes according to different contents, and can be used for professional instruments for food package 08/pack QS certification. In order for everyone to use the carton compression testing machine conveniently, the following will introduce the correct use of the carton compression testing machine.

1. Determine the safety and pressure resistance of the carton and the quality index standards of the code

The above two indicators can be obtained by formulas. The determination of the indicators varies depending on the domestic and foreign sales and the storage period. In special cases, such as the carton is supported by the contents, the appropriate anti-pressure index value can be determined according to the actual situation. The code quality index must be determined by the formula.

2. Detection and processing status

The carton is pretreated for 24 hours in a standard test state (general carton users can go to an authoritative and impartial testing agency to test unconditionally) and then re-test to make the moisture of the carton reach a dynamic equilibrium state.

3. Precautions for sample extraction

In the trial production stage of new products, the strength of sampling samples after printing and die-cutting is about 5-20% different from that of non-printing and die-cutting. Therefore, the state of the samples and batch products should be basically consistent, and the sampling of batch products should conform to the principle of statistical probability. , After years of practical experience, the sampling samples should be drawn in 6 different 3 packs, which can reduce the risk of misjudgment.

4. Result judgment

If there is a box force value lower than the pressure resistance index of the carton tested in the standard state, it can be judged that the carton is unqualified, and the discussion on improving the stacking test efficiency: stacking testing often takes a long time, which is economical and effective. The method of assessment is still in the exploratory stage.

5. Determine the average value of the standard safety stress resistance

Then the average value of the standard safety pressure resistance of double corrugated boxes should usually be 1.15 (15% higher than the safety pressure resistance value), and the average safety pressure resistance of single corrugated boxes should be 1.18.

Detect the peak pressure resistance of 6 sample cartons under the standard state, and calculate the arithmetic mean value of the peak pressure resistance value of the sample carton boxes. is not eligible.

How much do you know about the correct use of the carton compression testing machine? After reading the above content, everyone must know something. To improve the accuracy of the test data of the carton compression testing machine, it needs to be based on the correct operation method, and every step should be done well, especially the sequence of the operation steps cannot be ignored.
