Monitoring scheme for pressure resistance of medical transport cartons
Abstract: Pharmaceutical products are often transported in the form of cartons. The compressive capacity of the carton is a prerequisite for ensuring good protection of the products being transported. In this paper, Labthink XYD-15K carton compression testing machine test sample compressive strength of the carton as an example, briefly describes the basic process information and test equipment, to provide a reference for the ability to monitor compression of the carton.
Keywords: carton, compressive capacity, compressive strength, crushing, deformation, stacking, carton compression testing machine, medicine, transportation
1 , meaning
The pressure resistance of the carton refers to the ability of the carton to withstand external force extrusion, impact, stacking, etc. without deformation during transportation. The pressure resistance of the carton is an important performance of the carton, and it is a comprehensive manifestation of the protection of the transported products. The advantages and disadvantages of the carton's compressive capacity are mainly related to the reasonable combination of paper, structure and size design, side pressure strength, processing technology, moisture and stacking mode of transportation. If the pressure resistance of the carton for transporting medical products is poor, in the process of transportation, the carton is subjected to external force such as extrusion and stacking, which is prone to deformation or even crushing, resulting in loss of protection of the carton to medical products. . Therefore, strengthening the monitoring of the pressure resistance of the carton is an effective way to prevent the loss of medical products during transportation.

2 , the status quo
The pressure resistance of the carton can be tested by compressive strength. At present, the domestic testing methods for the compressive strength of carton are mainly GB/T 4857.4-2008 " Basic test for packaging and transport packages - Part 4 : Compression and stacking test methods using pressure testing machines".
3 , test samples
Corrugated boxes for packaging pharmaceutical products produced by a company.
4 , test equipment
This paper uses the XYD-15K carton compression tester independently developed by Jinan Languang Electromechanical Technology Co., Ltd. to test the compressive strength of the sample.

4.1 Test principle
By simulating the force of the carton during transportation, pressure is applied to the carton until the carton is deformed or crushed, or the carton is held at a set pressure for a certain period of time to test the time during which the carton is deformed or crushed. The pressure or time when the carton is deformed or crushed is the pressure resistance of the carton.
4.2 Scope of application
(1) This equipment is suitable for testing the deformation of corrugated boxes, honeycomb boxes and other packages under constant pressure, the resistance value under constant deformation conditions, the zui value when crushed, and the stacking test.
(2) This equipment is suitable for the compression test of plastic drums ( such as barrel containers for edible oil, mineral water, etc. ) , paper drums, cartons, paper cans, container containers (IBC barrels ) .
(3) This device complies with a number of national and international standards, such as ISO 12048, GB / T 16491, GB / T 4857.4, ASTM D642, ASTM D4169, TAPPI T804, JIS Z0212 like.
4.3 Equipment parameters
- The range of this device is available in 15 KN and 45 KN sizes.
- The test accuracy of the device is level 1 .
- The force value resolution is 1 daN and the deformation resolution is 0.1 mm .
- The test speed is divided into 5 mm/min , 10 mm/min and 12.7 mm/min , which can be set according to the standard requirements.
- The system is controlled by microcomputer, with PVC operation panel, and the test process is completed automatically.
- The system provides four test methods, namely, constant pressure measurement deformation, deformation measurement resistance, zui large crushing force, and stacking code.
- The LED digital display screen dynamically displays the sample number, sample deformation, real-time pressure, and initial pressure.
- Intelligent configuration such as limit stroke protection, overload protection and fault prompts ensure user safety .
5 , the test process
(1) Seal the carton sample, place it on the lower platen of the carton compression tester, and adjust the upper platen to make contact with the sample.

(2) Set the parameter information such as test speed, pre-pressure, and sample height. Click the test option and the test starts.
(3) The upper platen moves downward. When the pre-pressure is reached, the device begins to record the displacement curve of the sample with the pressure. After the test, the instrument automatically displays the compressive strength of the sample and the amount of deformation.
6 , test results
A total of 5 samples were tested in this test. The dimensions of the sample were 22 cm ( height ) × 32 cm ( length ) × 30 cm ( width ) , and the compressive strengths were 3405 N , 3462 N , 3419 N , 3455 N, respectively. , 3431 N.
